I was dealing with weird tacoing of leaf tips. Never had it before. Also the tips were light green. I think it was a bit of shock when changing light spectrum. Although the intensity was pretty low. Lamp was set only on 250w for a 5x5 space. Maybe it was a bit too low.
I think the issue resolved itself in acouple of days and after switching to 12/12 . DLI dropped and plants recovered fast. They seem to grow beautifully now.
