These guys are from seed and seem to be having an issue in the fox farms ocean forest. Any one have any ideas?

How close are those lights? & what kind, t5? Looks like light burn/stress on gsc and crack. Possible cal/mag deficiency. . .

Check out some mag deficiency pics and threads. That may be an issue. If you think that may be the cause try a very light foiler spray of epsom salts. It usually effects the lower leaves and not new growth though. Good luck!

I was going to say calcium as well, waterdog is right though those kinds of issues usually show up on lower foliage first. Seeing that your 400w was only 5 to 6 inches, is leading me to believe that was your issue. Hope it clears up!
Happy growing!
