Well I'm new to indoor growing and it shows. I guess I had the light turned up too high. In a hurry, I must've glanced over the part about 50% dim. They showed a little bit of lightening around the edges and were curling the tips down a little. Hopefully I didn't hurt them too bad. They're growing faster then any other plant I've grown. They're already working on the 3rd set of true leaves. They started with 1,3,5 leaves. The cotyledon are still green. I hope turning the light down to 50% and removing the domes will help. I underestimated the power of these lights. I put my seedlings out in the spring sun to bo I'll effects so I figured these couldn't hurt it.
