Hey guys im a first timer and i have a problem i cant figure out. I am growing in an ebb and flow system inside a stealth cabinet. The plants are starting to brown, or rust a bit. It seems that this could be a number of things. Here is all my info.
These where started from seed about a month ago. They started in rockwool and after they developed first set of leaves i put them in the mister system where they where misted with lite nutes, once roots where coming through the rockwool i transplanted to 4in cubes and moved to flowering room. I am using dutch master nutes, full strength, a 600w HPS air cooled light with ballist outside of cabinet. When light is off the temp is about 77 with 40% humidity, light on it tops out at about 88 with 65% humidity. It was running hotter than that so i got a little 95cfm blower and that helped a bit. There is also 2 circulation fans in this small space. The light is about 2 feet away from canopy. I check and maintain a ph of 6. For the most part my plants look pretty good. I will be greatful for any help.
Thanks
