hey all, so, ive got some pretty heavy yellowing, bleaching, and drooping with my girls. ive asked for a years now, and no one has been able to answer my why this might be. im using Ebb and flow with a air stone in the bottom of each buckett, RO+DI water, ph check 2x a day, top offs, res changes 1x a week. michorizae, ATAMI nutrient line................ ive got 3hps bulbs and 1 MH and only the ones under the MH have stayed green, the rest have turned yellow and begun bleaching, wilting etc.

My question: Do MH and HPS Bulbs cause different nutrient uptakes? and can HPS bleach and cause yellowing/wilting during flowering? could it be that HPS bulbs get hotter? whats the deal, yo!
