biz..are you having "male" problems?..too many, I mean?..or hermies?
undue stress can promote hermies, especially in "less than perfect" genetics. I've also found that stress during the 2-4 week of seedling, seems promote more males. Those weeks, try lower temps(65-70) higher humidity, and 18/6 or 16/8 light cycle, under as much blue spectrum as you can muster.
