Hi mate, she is looking really healthy and I wouldn't worry too much about that unless it gets worse. Could be the start of a calcium deficiency but I personally would not worry and keep and eye on it but it looks like natural dies off of stomata where the environment hasn't been ideal. I hope this helps, good luck and happy growing

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?

Black tips and spots on the leaves I'm having problems with the leaves. I estimate that the plant has about two or three weeks left to live, and I don't want to have issues now. Some tips are darkening, and spots are appearing on the leaves

4 days without water I had to leave for 4 days this past week. Gave both plants H2O before leaving but I came back and one of my plants has some ugly yellow and brown leaves. Do I need to do anything to correct this or just get back to my routine feedings?

Yellow-ish leaves and brown spots I ran into a small problem. The leaves of my RQS Critical are getting quite yellow and brown spots appear on some of the leaves. PH is kept between 6.1 and 6.5 while growing in organic soil. I feed according to the BioBizz schedule. Curled leaves have already been fixed.
