I switched from FloraNova to Super Nutrients (Super Veg A & B) for this round . I follow the directions to the letter (1200 ppm right now). I'm switching to 12/12 today, so I will be going to Super Bloom (A/B) from here on out; maybe the nutrient change will make a difference??? I waited an extra week in Veg. to try and shake this problem, but I gotta move forward now.

I can't really see how they could be deficient with that high of PPM. The main changes are the C02 which keeps it around 1500ppm during light hours (also adds some heat) and the 1000watts (from 400). Could it be radiant heat??? If it were nutes, I was thinking maybe FE (iron)???

Thanks for the feedback.
