Yeah it isn't good. Back the light off and you will be amazed at how the plants respond. Wilting is a sign of stress and stress isn't good even with the extra light they get.yes thats the best thought i could come up with...thanx man but as soon as its not burning them is there any problem with that?
Well that is already a good distance. You are measuring from the highest leaf to very bottom of the hood? I start my 400HPS at 65 cm at two weeks and then work my way down to 30 cms by four weeks. It sounds like it may be some other problem. Let your ph/nute situation stabilize and maybe that will fix it.My light is a 400W MH and its about 50cm over the tops. what do9 u think?
