Has anyone had plant issues caused by to much light?. I noticed when I turned on my 320w hlg LED plants where not liking it. I had is raided as up as far as it would go.. Plants where not responding well to it. I took it out and replaced with a 315w CMH. I'm seeing improvements in plants health withing 24 hrs. I do not see the same issue with the GC 420w led. I built the HLG using 2 3.5k boards and 1 4k board. I need to do more testing with it and see.
Ive been playing with higher [leaf surface] temperatures with LEDs lately. Compared to an HPS the leaf surface temperature is generally 5°F lower. Im running my air temps up to 84°F and noticed they can take more light.
Ive been playing with VPD as well...
