Might need some more N-def, if yellowing underneath. At top could be other things, though. Ensure pH is proper. It's a false narrative that you need to greatly reduce N in flower phase. the plant needs plenty of N to build buds too. 120-130ppm N, if you calculate from guaranteed analysis labels. (cumulative total)

Many of my plant's fan leaves, especially lower down in the plant are turning yellow. Is this normal? I think I'm on my last couple of weeks for flowering, so I'm not sure if it's just part of the process towards the end. Should I remove them, or just leave them there?

Hojas Amarillentas - Lemon King - 4-5 Semana vegetación Mis plantas se están colocando amarillas. Estoy a días de pasar al ciclo 12/12 ya que regué de forma foliar con Big One. En caso de ser ausencia de nitrógeno, como podría resolver la carencia. Muchas gracias por sus valiosos comentarios.

Friends need your help! the leaves turn yellow at the seedling stage!Friends, help me figure it out! First I will describe my conditions! - Tap water 110 ppm - LED QB288 Rspec 250 Watt light works at half the power! - Advanced Nutrients three-component Fertilizers Micro Grow Bloom now I'll tell you how it was! after they have sprouted! they were planted in the system! I made the solution on the recommendation of the fertilizer manufacturer! I added 1 ml/l of each component and it turned out 410 ppm! The second week I changed the solution completely and added 2 ml/l of each component, it turned out 600 ppm the yellowness on the leaves appeared after the first week! I thought it was a magnesium or iron deficiency! and I changed the solution and added 2 ml / l of fertilizers! I keep the ph of the solution within 5.7-6.0 drip irrigation works constantly! The temperature in the box is 23-25 C - humidity is 40-60% Inside, there is a fan on top that turns 360 degrees to blow the plants!

Yellow spot on my leaf. :) PH fluctuation ?(Water change) I had set to 5.5 PH and waited 20 minutes. I put in my fertilizers, everything was fine. The next morning the ph had dropped to 4.7.. So I put it back up. The next morning yellow spots appeared on the leaves. Did you confirm that is due to ph fluctuation ? Thank's

Organic peat control I think my plant is being eaten but gnats and it looks like nutrient damage on it but I haven’t given ANY nutrients to it. What should I do? Can you diagnose my plant? Any remedies? I heard cayenne pepper can be used for a pesticide is there other things? Does Neem oil work well?

Too much light or other deficiency Too much light or some other deficiency?
