Athosanswered grow question 6 years ago You are using coco nutes with soil? Anyway, I see rust spots on upper leaves, which is calcium deficiency. There's also signs of nute burn, bit since I see no information on your feeding strength, I can't comment on it, you may be feeding too much, too often or both and if that's the case the calcium issue it's probably lockout, if this is the case a flush would do good.
