Bloque de nutrientes?? Ph?? O falta de calcio y magnesio??
the bottom leaves have a yellow color, the smallest ones fell off completely. The upper leaves have yellow tones at the tips. I'm using biobizz nutrients and following the chart exactly as indicated in all the waterings. Could it be nutrient lockout?

Can anyone tell what is causing these yellow tips on new growth on this plant?
I noticed my DLI was around 42 at the top of this plant so the light may have been too strong, or it could be a nutrient issue? Using CoM Stonington soil, plant is 26 days old. Haven't added any nutrients to the soil yet.

Yellow leaves
Hi guys, unfortunately because of an emergency I had to leave my 2 babys with some friends for three weeks. At the bottom some yellow leaves and like burning signs. I don't think it's because of over nutrition. They didn't get any for three weeks. Might be not enough nutrient?

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?

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.
Older leaves have brown/red rusty spots and looks like dying tissue in between the veins. Burnt tips, and yellowing leaves. The soil was really dry and my PH meter was 0.4 too high. I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff. Runoff was PH: 6.1 EC: 0.8

What are my leaves telling me?
Is this light burn? Nutrient deficiency/excess? It is only happening on the top leaves, the lower leaves are just fine. The light is rather close to the plant, but she is outgrowing my tent. Thanks in advance for the help! I really appreciate it. 😀

Leaves turning a yellowish color
My plants are turning a yellow color. The two in front were shorter than the one in back, so I raised the two in front 4" so they all received the same amount of light. Any ideas?

Feedback/checkpoint/thoughts
Hi every1👽😌Started week 7 of flowering today. How do they look to you? Is there anything I should pay special attention to? I think I may have overfed or overwatered them last time - I’m not sure which one - which could explain the leaf damage. What do you guys think overall?
