Has anyone experienced led light burn with spiderfarmer sf4000 or sonofarm4000.. lights 24in above cannopy and leaves and buds burnt.. tent temp approx 78 degrees
Thanks for your response.. so this is my second run.. first one i did not have this issue.. im thinking a potassium issue...looks like light burn?? in veg all plants are vigorous.. just in mid flower started having this issue..
im going to try to leaving it up high for a few days.. then if that doesn't work im going to try and dim.. its not all the plants just 2 .. so they are pretty bad .. but i dont want to take away from the rest.. it looked like mag deficiency at first so i tried to correct.. but didnt ..
I'm having some issue with leaf curling with a spider farmer 4000..I had it over 30 inches up...had to keep the dimmer at 40 percent otherwise my leaves would start to curl

No issues when I ran the SF4000. I think I kept it 26" away? I'm running the SF2000 right now and no issues with that either
