Hi, new forum member here. Lookin for some help.
I’m in day 27 of flower. About 4 days ago, all of the uppermost leaves closest to the light turned really yellowish lime green. I could tell it was light stress, all of the leaves on the layer just below were fine, as were the ones in the corners of the tent. I backed the light (1000w HPS) off from about 20” to about 28” (I’m at the top of the tent now)
Around that same time, I also applied a feed really heavy in P, which I’m thinkin may have caused lockout of S and Zn. I’m also slowly dialing down temp & co2 at this phase.
Other than the lime green leaves, the plants look great.
Are these light bleached leaves a concern? Will they return to a normal shade of green now that I backed the light off? Should I consider dialing back the light to 750w?
Any knowledge or tips would be greatly appreciated.
