So I have been working on my indoor grow for two years. On a budget of course. When I first started i received a free 250w MH fixture so I used it for blooming. Free is free and it worked. Decent buds. My 8wk indica took a little longer to finish 10-11 weeks. Which was fine. The bud was good and no real complaints with the MH. I have since upgraded to a 400w HPS. Btw my grow tent is hxwxd = 5'x4'x2'. I have come across and issue that has plagued me for a while and I think I've narrowed it down to the lighting. Under the MH no issues. Under the HPS, around 3 weeks into bloom, the fan leaves from top to bottom begin to yellow. The rate is faster at the bottom, but it affects the entire plant new and old leaves. The green fades to a yellow, then death of the fan leaves. This obviously begins to affect the bud and I am forced to harves early. I've tried switching nutes, soil, water to no avail. The issue crops up every grow on every plant. The light fixture is about 16" above the tops of the plants. Temps range from 63-87 with 55% humidity. I'm using 2g pots right now, I even have a plant in a 3gal and same issue.
Is this a light bleaching issue? I'm not sure how else to describe without pictures. I'll get those asap. But I mean its straight forward, the plants and leaves look healthy and lush during veg then the leaves begin to lose the green and go yellow on me 2-3 weeks into bloom which is way too early.
Any suggestions are worth their weight in gold so please give me ideas.
