It doesn't look like light to me from the pics. You'd see the burn across the two big fans. It looks great except for the new growth though.

That wouldn't be over feed? Just went from dixie cup to terra pot a week ago with nursery brand organic soil and some 8-4-6 organic fert
i am definitely not a professional on the matter (i'm also back to growing this year since it's legal after years of not), but as far as i've read on here, you shouldn't transplant/give nutrients til the 5th node.
if i'm wrong hopefully this will give you a bump and you will find your answer. good luck

Some strains need some extra calmag when growing with LEDs.
More information on your grow is needed for someone to give you more help in diagnosing the problem.
Like medium, nutes, water, etc.

@koalajesus had a thread about discolored leaves from some intense LED


You've already dimmed and raised the light, but hopefully this provides some insight to help.

Hey! This is does look similar to the growth discoloration I was experiencing, but maybe to a lesser degree.
It definitely was my lights for the highlighter leaf problem I was having and making the proper adjustments (got a dimmable light, changed height and intensity) my problem resolved with new growth looking healthy.
Sucks that some of the highlighter did burn on my plant, but like I said it went to a strong degree.

This leaf has the varying degrees of health, recovery, and burns from the fix.

Also, I think Puffone3182 and I both have some excess N causing the dark green leaves. I just recently flushed my medium, waiting on new growth to develop and see just how green it becomes.

If you had a 300 watt (from the wall) LED on a seedling at 100% and 18 inches, it's probably light burn. Now that you reduced the power, wait it out and see if the new growth looks better.
