Female?

I have two plants that are about two weeks old in vegetative state but it looks like female pistils are already showing? Is this possible? Do I need to switch to 12/12 already?

Unless u ordered some sort of auto-flowering seeds, then no, not possible. Maybe if they were from clones taken from a fem. don't switch to 12/12 till UR ready. If ur talkin about the little spike lookin things that grow out of the nodes, then this is totatlly normal, all plants do this, male and female. U won't know the sex of the plant til AFTER switching to 12/12

sounds strange to me , you sure your looking at the right place/thing here ? we need pics ...........

Yep it must be normal because that's what it is.

Just swithch em to 12/12 when ur ready just plant on the girls gettin twice the size during flowering... haha! kinda like gettin married!
