Crpehdmanswered grow question 4 years ago I haven’t been able to do much about the heat, however there is great air flow and circulation, everyone is also growing well so not so worried about the heat. I did however skip a weekly feeding, have started back up again, this has now been 2 more weeks of weekly nutrients (b52 and sensi grow) I haven’t had any more Burt tips or leaf discoloring. I believe my issue was to much nutrients at to young of an age.
