Appreciate the response my friend. It is literally driving me insane.try uploading a couple at a time? itll happen to my every once in a while but usually if something like that happens its the site and not just you haha
if its mainly the lower leaves that are yellowing, its likely a slight ph or light penetration issue. Whats your soils ph? It should be 6.2 ideally from what i know about soil/soil-less mix's.
I Pulled the worst AK and the worst White Domina out for better viewing. They are the worst out of the group. Next watering they are getting a 50% feeding of bloom to see what they do.what nutes are you using and whats their NPK values? It doesn't seem like it would be a PH issue since those values should be fine in a soil/medium grow. If flower production is unaffected, then your probably right its a N issue, though during flower they don't need a lot of N. If you juiced the nutes till you saw a lil burn, try flushing again and giving a 50% feeding of bloom nutes, most bloom formulas still have enough N to keep the leaves green.
