So it’s my first grow, hydro, scrog setup. Temp is 78 lights on and 68 lights off, 50% humidity, 1200+ ppm cO2. Using GH trio and attached schedule I’m following for nutes. Things are looking ok, but recently been seeing some whitening of bud tips and topmost sugar leaves. I raised the lights quite a bit (California light works 1000w with uvb cycling 30 min for a total of 2 hrs per day) and hope that remedies the issues I’m seeing. Should note that some uppermost leaves are curling upward. Do you think there is also a nitrogen toxicity issue given color of darker leaves? Any thoughts would be greatly appreciated thanks
