Interesting, the theory you describe makes sense. How much do those T4-2100's output each?Well thats the thing... i didnt mention that i was seeing some very light bleaching up top because i didnt recognize as such. Never had that problem before. So after reading a specific article/pics... i saw that is what is going on with my plants....
And apparently that bleaching is an indication that the leaves are working very hard sucking up as much nutes as they can and "killing" themselves doing it, and isnt enough so they start canabalizing the lowers looking for more and those are the deficiencies im seeing, likely.
Depending on the intensity of the light and how rapid photosynth is... feeding more nutes can be even more damaging.
Might be barking up the wrong tree, but... its the only thing that makes sense right now. I mean... i just potted up a week ago so salt build up is very unlikely, pH is something i have always been meticulous about and my air exchange isnt so bad that it should cause this, i doubt...lol
