I bought some fem. white widow from a site called cannabisseeds.com and i grew one out to be a mother plant.there was no stress on that plant other than i over watered early in it life but it snapped out of it and was otherwise very heathy!i turned the lights back when it was about 20in. tall month and a half or so well, (i took clones of course)guess what?MALE!not a hermi a freakin male.so,i grew out a few moreand got 1 more male the other 10 arent there yet so i wont pay the extra for fems next time.just a thought.
