Is this a sign of light stress, been watching it a couple of days and I believe it’s getting lighter so I just lowered my light from 100 percent to 75 percent because I’m out of vertical space
That does look like light stress, are the lower, inner leaves ok? I have the same issue, let them veg about a week too long, started getting bleached leaves, went from. 190% to 60% and it helped a lot!
