Ive always had a theory on the high male thing with autos.
@Mossy and i talked about how sometimes pre-ferted soil can cause a higher male ratio when starting seeds directly in it.
I typically start with Black gold, and thats it. Nothing else until sex. No bottled nutes, nothing in the soil. Male and female ratio is awesome. Then when i started doing direct germs into pre-mixed soil, my ratio went UP again. The biotabs as well as the other items i place in my organic soil have a lot of ferts in there. Not a TON but enough i think to cause this.
This was and is the whole reason that i developed the tier. I would start them in virgin, non-ferted soil till sex and then into the next pot with out disturbing the rootball.....time to test this theory again and see what happens if i tier them and what the ratios are then.
