Im currently growing bumble bomb under a 600w hps in an nft system. Im about 5 weeks into flower and alls been well apart from some light bleaching due to height. Ive lst'd the plant away from the light and this seems to have solved the problem. But now the leaves are curling under. Almost claw like. If i was in veg id assume n tox but can this happen in flower? Im using hydro max a+b and big bud only. I checked the ph and it was at 6.9 so i made adjustments and got it to 6.4 but i spilt my ph down in my boot grrr so i have to order more which i am. But can anyone give any suggestions as to if theres an issue? I may just be being abjt over cautious i tend to get like this when the end is near ... im trying to upload pics but doesnt seem to want to work...

People love helping but they do not want to here quite close, it is a turn off. They want to know exactly how far away the canopy of the plant is from the from the base of the light frame.
Do you use a glass cover and vent out the air from the light frame?
How far was the light from the canopy when the burn happened?
How far is it now?

The light is approx 5-7 inches above the highest part of the plant. When the burn happened the plant was about 2 inches away. I managed to get the light higher with abit of fiddling and lst'd the plant to create more space between the light and the plant. The light is in a glass cool tube with air being vent out the tube and out the tent. Temps in the tent are sitting between 24c and upto 28c when it has been hot (30c+ outside). The humidity in the tent is at 60%. I have a better pic where the light can be seen i will try and upload

Let me edit the way I said that. I'm tired. I'll check back later to see what it says and to see what others think. I'm curious if you are still way to close.

I think i probably am but there isnt anywhere else for it to go.. the lights as high as i can get it ..all i can do is try lst it more. Its my own fsult really i vegged a little longer than i intended due to high temps i was struggling to lower (before i had the cool tube and during heatwave) a friend advised me to stay in veg until i could get the temps under control so the plant wouldnt herm. Being relatively new to growing (4th grow) i took his advice and stayed in veg longer but the result was this beast of a plant.
