Can someone please help with yellowing leaves? They are older ones. But i dunno if there is a deficieny or overwater or poor air circulation. Day 69,week 10 in pre flower stage.
Don't sweat it. Older leaves towards the bottom of your plant will be some of the first to be cannibalize by your plant at one point or another. If you see this move to newer growth THEN you got problems-likely nutritional/pH related.
