ec during flowering

Old salts will be washed out with the run off with every feed. But opting out of some of these cookies may have an effect on your browsing experience. June 1-2019 Start off, with just 0.2 points over your BG EC, and monitor the run off from there. Week 1-3: The Flowering Stretch. This kind of cleansing technology really improves water quality by filtering out any salt build-ups, thus increasing the absorption of nutrients by the roots system. Soil For the most part, the pH balance is more important to soil growers than EC/PPM values (although an EC meter is always a good investment). But if you’re checking EC for the first time on bigger plants, then you need to monitor the levels for a couple of feeds to get an idea of the right levels. If it is left to sit in trays, it can pick up old salts from them, and alter the actual EC, so your reading will be inaccurate. Too much of a change in EC either way can shock the plants, so gradual changes should be made, unless there is a major problem. If the EC of tap water is 0.3 or higher, the water should be treated with a reverse osmosis filter before adding nutrients. Testing EC and pH simultaneously is a good way to optimize operations. You need to have at least 10% run off with every watering when you grow in coco. I can't seem to get much past 1.3 or 1.4 before I start to get build up to the point of wanting to lock out, or nute burn. Get around 10% runoff, and collect it as it comes out of the pots mid flow. Regularly add plain water to the nutrient solution to replace the one absorbed by plants. The only countermeasure is leaching the substrate thoroughly with water, add a diluted nutrient solution, runoff, and replace with new balanced nutritive solution. The most used scales for measuring the concentration of chemicals in water are electrical conductivity (EC) scales, and the parts per million (ppm) scale. Hydroponic and aeroponic grow methods use direct feeding devices, which require a perfect control of the chemical compounds and values of fertilized water. Place each sample in a clean jar and use a calibrated EC meter to measure each of the samples. This will count towards your final EC. When it does, it leaves salts behind, and can cause EC levels to rise quickly in the medium. If the nutrients in the medium are at a higher EC than what is in your plant, the nutrients will force their way into the plant, causing nutrient burn and excess. With three separate solution mixtures, you have a higher level of agency over your plant’s nutrient intake at various stages of life. a pH of 5.5 - 5.8 * without co2 injection and control. During the day, when the sun is out and it’s warm, no lamps will be on. Here is a chart, that can help you convert PPM into EC, it will also show how confusing the different PPM ratios can be. Foliage growth can become harder, darker and brittle. To lower the EC level, just increase the runoff to 30% of the solution. It’s best to stick with EC, as that is a flat reading no matter what meter you use. When you’re happy, you can adjust the pH and feed it to your plants. Necrosis generally appears during flowering. As the plant drinks the water, and moisture evaporates from the pot, the salts will be left behind. Coco should be kept saturated at all times to prevent EC spikes, and these need to be taken into account when testing the feed to find the best EC for your plants. This dramatically reduces the risk of salts build-up. The FloraMicro solution targets the flowering stages of growth. This will cause your plants to be sitting in a medium with too many salts, and it can burn them. Pure distilled water does not efficiently conduct electricity. By monitoring the EC (Electro Conductivity) of your nutrient solution, you will have an idea of how much of the salt based nutrients are available to your plant, in turn you will know how much you are feeding your plant. As the nutrient ion is used, it loses its charge too. Only ever feed just water, when you’re flushing before harvest. During the flower stage, optimum parts per million rises to 1000-1100. Now, you need to feed your plant with a nutrient solution that was the same as yesterdays, same EC, same pH. If the BG EC is over 0.6, you should consider using reverse osmosis water, or diluting the water with mineral water to reduce it. You’ll want to monitor pH and EC, at least weekly. I'm just curious as to how high you guys and gals get your EC during flowering. Keep the EC low unless your plant asks for more. Phosphorus and Potassium are required in high amounts during the mid flowering phase so better to be slightly too acidic than slightly too alkaline. If the EC of the runoff falls, to 0.7, then your plant needs more nutrients. Consistency is important, small gradual changes are advised, anything too quick can cause damage to the plant and cause shock. On the opposite, a low nutrient concentration causing low EC forces more water uptake from the roots. Keep constant record of EC and pH measurements. As the water in the medium is used by the plant, and evaporates, salt based nutrients are left behind. This tends to happen only when there are big changes in the EC of the nutrients. The most typical signs of this are drooping or yellowing leaves, irregular leaf shape or dimension, or brown spots and burnt edges. Very young seedlings or clones will appreciate receiving water with a PPM reading of 500-600 PPM. this page has helped me a lot but i will need guidance from the chat window and the all knowing growers there. Water evaporation increases the nutrient concentration. The higher the salt concentration, the greater the electrical reading. Try and collect the runoff as it exits the pots, and take your reading from there. Keep it simple, and use EC: In full hydroponic systems, such as DWC, NFT, and other methods where the roots are suspended in water, plants are said to be able to take a higher EC, than a plant in soilless mediums like coco. Growing cannabis in hydroponic systems like DWC, NFT, and coco, is usually done with “salt based nutrients“. For example, if you’re seeing a 6.6 in your runoff during flowering, try 5.6 to 5.8 the next time to bring it down a bit, again measuring the runoff. 38 days, still increasing EC and fattening bud Between the 4th and 5th week of flowering we see how potassium comes into play. In the chart below, you can find general guidelines for optimal EC at different life stages, however, there are differences between different nutrient lines. If it is lower than the feed you have been giving your plants, then increase the EC of the next feed by 0.2. if it is higher, than reduce the EC by 0.1. This is because plants growing in hydroponics, will have an airstone in the root zone which will provide air directly to the plants roots. Under normal conditions, the EC in the growing media and runoff should be just a little higher than the nutrient solution in the reservoir. The drier the medium gets, the more the EC will rise. Electrical conductivity is the electrical charge that moves through a solution. This will change the EC and pH of the nutrient solution. In worst case scenarios, an EC spike can damage the roots to the extent where they can no longer take in nutrients. Plants stop growing, staying shorter with smaller leaves. Test this water, and find out if the EC is higher or lower than the feed going in. When you find the right levels, and everything is stable, your plants will have access to the right levels of nutrients, and it will grow healthy and happily. Organic Vs Synthetic Fertilizers: Which Is Best For Cannabis? If there are sharp changes, there can be many problems that arise. Just as the nutrition needs of a plant change during its life cycle, its optimal EC range also changes: starting low, reaching a peak during late bloom, and going down sharply at the end. This should be collected as it is coming out of the pots. Some commercial growers are able to pump enough nutrients into their blooming plants without causing damage. Max 1.4 EC / 700 ppm * during Vegetative phase. When you have found that correct leve, you will see how much healthier your grows will be in the future. If your EC levels rise too high in an active closed-circuit system, it probably means that your plants are absorbing too … Feed this nutrient solution to your plants, in the recirculating system, and then monitor the EC and pH levels after 24 hours. It is mandatory to procure user consent prior to running these cookies on your website. You should always start a seedling off at a very low EC. Keep in mind that it is normal for leaves to turn yellow during the late flowering stage, and it is also normal for the odd leaf to turn yellow as your plant naturally defoliates. Other symptoms such as … Transpiration is an essential plant process that plays a major role in photosynthesis and the processing of carbon dioxide and carbohydrates. For the best results use a good EC meter, and let your feed sit for a few minutes after mixing before you test it. Clearly, cannabis plants enjoy increased parts per million as they grow. In the lab, EC is how the potential to conduct electricity of materials is measured. 0.8-1.3 for seedlings; 0.5-1.3 for clones; 1.3-1.7 under vegetative phase; In some cases, you may have a “PPM” meter, instead of an EC meter. ppm meter when mixing 3-1-2 ratio dry fertilizer in reservoir for VEG. As you water your cannabis plants in coco, the nutrient solution will wash through, and push old salts out. EC is seen as a more accurate way of testing the strength of a nutrient solution, and it is used by growers all over the world. Day 36 Day 40 Day 47 The flowering stage … To raise the EC, add more fertilizer to the solution, or change the nutrient solution. If you have reduced the EC of your feed by more than 0.4 points, the first test may show a slight raise in EC before it levels off on the second test after another feeding. EC levels during flowering* The nutrient charts are very useful as a rough guide to the nutrient concentrations week to week but it’s only through looking at the leaves, stems, roots, etc . Best EC for Growing Cannabis in Hydroponic Systems, Test your Nutrient Solution Before Feeding, Finding the Best EC for Cannabis Plants in Coco, This article is also published as a forum topic here », To edit this sidebar, go to admin backend's. It is important you get a good, correct reading of your feed, before it is given to the plants. Above all, the concentration of the nutrient solution directly impacts plants’ health, growth and yield. Your plant, and grow medium, will find a steady balance between each other. If the natural EC of tap water deviates too much of different fertilizer averages (based on an average EC of 0.4/0.5 mS), that difference in EC has to be readjusted. When your Cannabis plant is in its initial growth period, it should have an EC measuring 0.8-1.0; during flowering, the EC should be somewhere between 1.2-2. im feeding my plant at EC 1.65 which contains rhizotonic, cal mag, ionic bloom and ionic boost. If you’re below it, add small amounts of nutrients until the level is right. In situations like this, you can monitor the EC and pH of the reservoir, to help find the best EC for cannabis plants. This will count towards your final EC. This will help you feed them what they need, when they need it. The best way to avoid problems is draining the irrigation system and adding fresh solution regularly. You have to find the right balance, and feed the right amount of nutrients to the plant. Stir well, let it sit for a few minutes, then test it. So be careful of this factor. love the page by the way its deadly. The result is often fruits with a harsh taste due to the excess of salts in plant tissues during flowering stage. Check your EC and check that your EC meter is within range (use a conductivity buffer). A young seedling or a cutting (clone) will enjoy a ppm of approximately 500-600 and will respond positively to an increase of about 850 ppm during the medium and late stages of vegetative growth. Hydroponic mixes without media reserves require some N during the first half of flowering (usually 3-4 weeks) and less during the next quarter (10-15 days). This last one is also named total dissolved solids or TDC scale. And you should water everyday. The best EC for cannabis plants, is not set in stone, and each strain, and even each phenotype will prefer different levels of EC. When we add fertilizing compounds to tap water, these chemicals increase water electrical conductivity, and a greater concentration of nutrients in water results in a liquid, that conducts more electricity. On the other hand, if the EC of the runoff is higher than the EC of the feed, then you’re giving your plant more than it needs, and you should reduce the EC to prevent toxicity. If your EC levels rise too high in an active closed circuit system, it probably means that your plants are absorbing too much water, and not absorbing the nutrients. Always consider, that a plant might never fully recover from a nutrient lockout or an excess of nutrients. After watering your plants, your trays will fill up with water, this is your run off. As a general rule, plants will have a higher nutrient requirement during colder months, and lower demand in the hottest months. Water quality is very important, and requires some work. This is what EC is. During and after the vegging stage, your plants will want more out of their feedings so filtering isn’t really necessary. This will be your background EC plus any nutrients you have added to the water. Necessary cookies are absolutely essential for the website to function properly. A good EC (or ppm) measurement is made by collecting water samples from the reservoir, growing medium and runoff. To check the EC of the nutrient solution for your plants, you need a good reliable EC meter. You can monitor the soil using only pH and staying within the recommended range. This category only includes cookies that ensures basic functionalities and security features of the website. Water your plants from underneath once, so the roots will start searching for water and they’ll quickly grow towards the bottom of the pot. The Full Guide To The Best Cannabis Nutrients, Understanding N-P-K And What It Means When Growing Cannabis. These readings should be taken at the same hour every day. In this guide we will go step by step, and explain how you can find the best EC for your plants. This is the EC of the water you’re going to use, before any nutrients are added to it. If too many salts are removed, the nutrient level of the plant is higher than the medium, and nutrients will start moving from the plant and into the water. Feed the seedlings, and collect the runoff as it flows out of the pot. EC fluctuations can be interpreted as under or over fertilising. These cookies will be stored in your browser only with your consent. If you have any questions about finding the right EC for your cannabis plants, then feel free to ask for help in our cannabis growers forum. Different varieties of cannabis might require significantly different values of EC. The plant and the water, find balance, and there will be a certain amount of food in the plant, that is equal to that in the water. Not because the mix has been made poorly, but because nutrients can alter their levels under a number of conditions. If you go slightly over your desired EC, then add more water to dilute the solution. Less is more! very enlightening, from what i see all my plants are suffering with problems and it all stems from ec from what i can gather. As more salts are added, the electroconductivity of the solution will rise. Leaching the system with mild nutrient solution for an hour or more between changing the reservoir avoids a lack of nutrients even for a short time. And that’s a … “Hard” water contains high levels of calcium and magnesium, while “soft” water has so few ionic salts, that might require calcium compounds to be added to the nutritive solution. Sometimes you may find guides across the internet that use PPM instead of EC. If it has risen, reduce the EC by 0.1 point. In that case, the EC will tend to go down. If they are brownish in colour this is likely to be the problem. You want the cannabis plant to be able to use all the phosphorus it can at all times, but especially during flowering. NPK will change to 1-1-1 when switching to flower then 0-1-1 in later flower? General rule, plants will do their best at 1000-1100 ppm run off there.
