definitely lay off the nutes. maybe even water with straight water then go back in 5 min and water again to flush some out then start feeding lower doses on next feeding
Its hard to see, but it looks like you are starting to get the nitrogen claw as well. Sometimes plants don't really burn per se, but show you they are over ferted in other ways.
It was just moved outside from being under CFLs. It is getting the claw. I noticed that yesterday, then this today. Already started on plain water yesterday. So the two probably are connected. Plus the possible sun shock, I suppose. Thanks guys(or gals).
