Hello everyone, I'm a long time fan of this website and never made an account till recently. I have found this website to be more helpful then any other marijuana message board out there, and the people who contribute to be life savers even hero's. This is far from my first grow but I'm running into some problems week 2 into flower. On some of my tops (and only the tops) there appears to be a slight yellowing and I can't put my finger on whats exactly going on. I cant find any pictures of whats going on so I thought I would ask and see what you guys and gals think. This is my first grow using the Gavita 750 flex de fixtures and I have noticed that my plants vegging under T5's tend to be darker green and do not show this characteristic, but plants vegged under 750s have a slight yellowing. I am currently running a sea of green in flower in 1 gallon pots with BM6 (peat moss as my medium). Plants on the outskirts generally have a more green vigor to them compared to plants directly under the 750s. But from what my research is telling me its either a sulfur, iron, or even a magnesium deficiency. Any help with this problem will be much appreciated. If any more info is needed please let me know
