I have tried to grows using this light!! It has brought me nothing but problems, hung the ligh as instructed by the manufacturer. My plans have shriveled up and died. It seems to suck the life out of them slowly. It starts with yellowing leaves and the seems to create a defenciacy followed by levels curling up and firing. Any body have any ideas why.
My grow tent is 4x4 x8 6 in exhaust two fans.
I have never had any issues with my hid lights in same tent

Need some pics of the plants.
Lights wouldn't fry the plants unless they were on top of them.
Leds work better when the room is in the low 80's. with RH in the 60's.

I know nothing about this light, but he said he keeps it 48 inches above the canopy. That seems like quite a distance to me. Instead of these smarmy comments, someone who owns one of these should help the guy out!

Hey bud, I cannot comment with any experience with that light, I just bought the 600 Rspec from HLG and was told 50% at. 30" for veg and. 24" full power for flower. Adjust the light up slowly the 2nd week of 1212 until you reach full power over 5 days or so. Are you slowly moving the power up over the course of days as they suggest? At what point are you finding issues, is it only happening half way through flower? I know @PadawanWarrior grows under HLG lights, perhaps he can chime in. Also are you feeding the same as you did under HID? I believe LED plants need more food.
