Hey how are you..i need help right now!!! I have 16 plants about 1 month into flowering.... they are under 2000 watts hps air cooled in a 6 by 4 tent with intake and exhaust.... I am watering them about every 3 days with botanicare nutrients...bloom,calmag,karma,silica blast,and some flavor stuff. About half of my plants are turning completely yellow, almost like bananas, and the tips of alot of the leaves are burning... Is this a deficiency or is it nute burn? I though it was mg def. so i started foilar feeding with epsom salt but no results. So please help and tell me what i can do.. Right now they are lights off, so when the lights go on in a few hours i will; post pics.. Oh yeh they are 12 trainwreck,2 white widow,2 skunk #1....also the buds do not look full and compact like they should under 2000 watts. Maybe its just a slow growing strain? Any help please!!!!kiss-ass
