Brown, curling leaves?

HomeGrown_Medicinalstarted grow question 2 years ago

I have no idea what's happening here but the girls are showing some kind of deficiency. Browning, curling leaves. I have two 100w led lights above them and I use an organic dry fertilizer, I recently brewed a compost tea to try to get nutrients to them

Solved

Leaves. Curl down

Leaves. Color - Dark-brown

Hey there, I'm an organic cultivator in BC Canada. I also use dry inputs which either get amended in the soil or top dressed during critical growth phases. I brew ACT ( aerated compost teas) and make SST ( sprouted seed tea) for my girls regularly. From what I see in your pictures it seems to me that stomata has closed and transpiration has come to a halt. Possible issues that need to be explored are: 1. PH of growing medium (soil) should be 6.3-6.8 outside of these ranges specific nutrients will not be taken up by the plant also do not overwater! Your water should also be tested for PH and PPM make sure no chlorinated water is used! Let sit for 18-24hrs before using Watering PH ranges can fluctuate but try to maintain 6.3-6.8 for watering. 2. Container size. In organic gardening we feed the soil not the plant! use the largest container possible to maintain the happy balance of micro besties. 3. Micro beasties are what we are trying to create within our soil. These lil machines take up those amended nutrients and their secretions' are what the plant use as food. the mythology of organic growing flips upside down when compared to bottled salts based nutrient programs. 4. Where are you sourcing your meals, guanos and organic inputs. this is critical when deciding on how to build your soil. Some inputs need a "cook time" and others are ready to go without a "cook time" 5. Cal mag is your friend but make sure it is well sourced to avoid killing off those much needed Micro Beasties. When using and LED fixture the observation has been they use huge amounts of cal mag and become deficient way sooner than with HID fixtures. keep me posted and message me if you need any other depth in info. Good luck my friend 👊

High, These are all signs of overfeeding and nutrient lockout because of overfeeding. You can use flushing to get the build up nutrients out of your soil. But don't overdo this because then you create other problems like root rot. I would flush only 1 time and you can do this by slowly pour water onto the top of the soil, allowing it to drain freely from the bottom of the pot. Pour slowly, so the water doesn't overflow from the top of the pot. Use approximately four times the pot's volume in water to flush the soil. For example, use 1 gallon of water for a 1 quart pot. After the flushing you want the soil to dry out (almost) completely. After this you can continue watering like you are used to and start giving a small dose of nutes again. Happy Growing! 😋

Is this your Gorilla Cookies grow? I will assume that it is because some of the photos look similar (it's always good to start this question INSIDE the diary - you can find where to do that at the bottom of the page). Anyway, right off the top, I'm thinking you are not giving her enough water - .13 gals per day in a 5 gallon? That's pretty low - and what THAT says to me is that you are not flushing the nutrients you're providing her when you give her plain water so I think there is a build-up going on as well as perhaps some roots that are now dying because they haven't been getting the moisture they need. I would advocate two things: get yourself some ReCharge (it reactivates microorganisms in the soil) and then give her the best drink she's ever had... I'd give her one gallon of ph'd water and then another gallon of ph'd water with 1/2 ReCharge in it (if you want, a tsp or two of molasses would also help) and then let her dry out completely. Underwatering, while fairly uncommon among growers (if anything, folks think that more water = bigger growth and they end up drowning their plants) just isn't good for the plant on any level. At her size, I would expect her to be going through at least 1/2 gallon a day - but she needs the root system to be able to drink it. When you feed her, make sure you get just a little runoff from your pot... when you water her, do the same but try for 10-20% runoff. Always wait until the pot is super light (which means it's dry) before giving her something else. And always, always, always make sure the pH is good (at her age, 6.2-6.3 would be ideal for all the nutrients she needs). Good luck!

I will go for lights too close and VPD in stress day and night.

also, reduce your feed after the flush... looks overfed, so more likely lockout than a lack of nutrients. keep notes of what you do until you find that balance.. will be a faster learning curve, if you do. this works better of fairly consistent and not flip-flopping each week before seeing resutls... time and patience.. sometiems the things we do take months to see the problem -- like a Mg deficiency does not disply problems initially. when you see it, it started weeks ago.
