Thanks for all your help. Everyone here has been very helpful. They are looking even better today. I found that the heat stress may be because I turned my thermostat up a few degrees the other day during non lighting hours and forgot to turn it back down.Yep heat stress like IGLW said^^^^^
That is what you are looking for after plant issues. The new growth is what lets you know that things are going better for the babies.
You've done well, now just sit back and watch your plants take off.
