Hey Cjw, how's your leaf situation? Doing some strategic leaf pruning, can help a lot during flower. You don't want to get carried away, but fewer leaves equals less transpiration. Check out what Nebula has posted in the Tutorials on Defoliation first though. It can also help with air flow, to remove the old leaves down at the bottom, and bottom middle of there plant to allow better air flow. Also many people like to remove the bud sites down in areas where they don't get much air or light, since those never really get much to them.
What's yer night time temp? If it is on the cool side, like 50-low 60's, adding a little heat can bring it down. Can you improve it with better air exchange?
