looks like LED burn to me. I had the same thing when my LED’s were 16-18” from the canopy (seemed more severe under my LED with more reds for flowering). I’ve since raised the LED’s to be 24-30” above and don’t see issues like this anymore with new growth. The damaged leaves will not change back to green but you should stop seeing new leaves affected.
