It's a sign of to heavy nutrients. Your ph should be at 5.8, your at the low level right now. Your ec should be at 500 ppm 1.0 ec for now. Just adjust it up in ph and down in ec. The new growth will improve. Cheers

Nutrient burn?Hello I have one plant with yellowing leaves that are also curling downward. Only one plant of 6 has this problem, I suspect maybe this one is just sensitive to the nutrient rich soil? I am using fox farm happy frog and have added no other fertilizer. What to do, flush all?4y ago

They were slightly overwatered, the soil PH of 7.1 to 7.3, lacking phosphorus, maybe magnesium to. Branches from the sides are stretching, but I noticed thet lower leaves started to turn yellow a little at both. If anyone knows good advice to help them out, I would be grateful.๐

Cotyledons TwistedThis happened to the last seed, so maybe it is me. I'm worried it won't point up. Second day seeding. I wet the soil when I planted and has been under a dome. I have not watered again. DLI is 12 and PPFD is just under 200. Any advice on what I am doing wrong?Leaves. Curl down

Leaves drooping after transplantMy one plant has been starting to droop and the leaves are wilting down a day after transplant. I know this can happen from transplanting as the plant is going through additional stress but is this whatโs going on? If not, any ideas? See photos week 9. Thanks!6y ago

Calcium excess, which led to potassium deficiency? Or just light burn? Or both? What's wrong with my girl? Please, help.I've been giving her BioBizz in accordance with the schedule, including CalMag. Using tap water (250-300 ppm). So my only guess is calcium excess, which led to potassium deficiency.
However, only the main cola is affected now. So I also suspect light burn.
What's your opinion?4y ago
