Feed them Magnesium, These aren't burnt they just don't have enough juice (calmag) to photosynthesize :) :muscle:

Thanks! Ph must've been to low cause I was feeding calmag. I raised it to like 6.4 and they look much better now.

Hi, I'm still new to this.
I had a leaf problem on my seedlings that turned everything yellow fairly fast.
Originally thought I'd caused a pH lockout but in hindsight it was my LED QBs were too close and intense even though it appeared to me visually not that strong.
Seedlings looked done for but have since recovered well and fast.
There's photos on my latest diary of them being yellow to green.
By any chance is there a high ratio of red light wavelengths to other colors in your lights ?
