Thanks guys. I changed them out today just to eliminate that as a source of my problems. Temps have been my biggest problem, 4 hps in an 8 x 8 ft. flower room. My lamps arn't the enclosed kind, so the heat just disapates into the room. I've got 3 exhaust fans on 24/7 to help with air exchange and a portable swamp cooler to cool it all down as much as I can. I still see 90 deg heat in there on a hot day. Lights on at night to help with temps also. The lamps where last changed out last july so they where due anyway.
The flower and grow rooms are in a converted shed, so insulation is minimal. I used 2 inch foam on all walls and the ceiling which helps a bit, especially in the winter. I think what is happening is that a combination of factors is causing stress so the plants just sit there. I have one that just keeps making more and more bud, though it is mostly foxtails. About two ft. of foxtails. Its been doing that for over two months now without maturing. very strange. The room is sealed up well, no light leaks or anything as that was the first thing I checked. And I did have a root fungas that I treated with h2o2 a while back. So stress is probebly the major issue here.
I'll give it a week under the new lights and see what developes. The strains are Master Kush ( the one plant that keeps making foxtails), Nirvanas Ice, THC Bomb, and Wonder Woman.
Thanks for the input folks, I appreciate it.
