Yellow New Growth After Tea Yesterday

[Dane Warner]

lights are on 24/7

I think your right, I put established plants in the green house and after 5-6 days the same yellow/light green appeared on all the strains. Night time temps50 degrees, day is 60-70. It will be a month before it gets warm in there. Got any suggestions?

Its an iron thing. Either ph issue or supplement iron.
