Hi all, this is my first grow, sort of a fumble my way through job! my plants are into their 7th week of flowering now, we only started using nutes since week 4, but only in light amounts
the plants are generally healthy but over the last few days one has had problems with the leaves turning down & bright yellow almost dayglow patches on the dark green leaves, any ideas what could be causing this?
some of the other plants leaves are turning up, as in the 3rd picture, is this a symptom of heat stress? using a 400w HPS light, bout a foot away from the tops with a small fan circulating to cool abit
Any advice would be appreciated
