I have 2 NL and 1 GSC in autopots under 2 96x3w reflector series led's. Ph in the reservoir is 5.9 and the ec is 1.0 dropped down from 1.5 after I accidentally misread quantities on the bottle. Temp is a steady 26c with the lights on. Now I know the early/first leaves show signs of nute burn....that's under control now, the problem I think I have is light burn/bleaching...I originally had the lights 18 inches away but have now moved them up to 36 inches.
I have added calmag to the reservoir along with the other nutes from the start so I don't think it's a calmag issue but too much light
Can someone confirm this please or correct me if I'm wrong

That looks like nute shock to me. I'd think 24 inches would be far enough, as they are young yet, but there isn't any curl to speak of, so it doesn't scream light stress. I'd see how they recover ow that you've got the nute levels right
