How often do you add nutes, and what is the N-P-K numbers on them? Sounds and looks like you are giving too much humidity, too much heat, and likely overfeeding. You mention foliar feeding daily at 1/4 strength. This may be the problem. 1/4 strength, four times a week=100%. 1/4 strength, 7 times a week=way too much)

Living in the desert with an outdoor flower room, I usually never give the ladies anything foliar, except perhaps an occational spray to correct any deficiencies (usually nitrogen) that may occour. But when I do spray, I raise the lights till all is evaporated. (The little drops of water act like millions of tiny magnifying lenses)

I would recommend going with a regular feeding schedule without the foliar. Especially if you are having heat issues. (steamed cannabis doesn't grow well)
