Wow 11 dudes.. sry man..
i just got 8/10 females. was just counting on 5 of them to turn so had to throw (yea.. throw) away 3 females
anyways 1 girl has yet to shown preflowers but it was a FEM seed so i know that that 1 is a female but im 7 days into flower and bitch just wont show.. all the others have.
ah but a clue! my theory is that all my plants who have shown pre flowers are indica dominant whilst the one that hasnt has been sativa.. maybe that has somthn to do with it?
