Nice.. thats what i was going to say.. Sometimes its hard to tell too early..I'm growing Vortex right now, too. Just sexed them the other day in fact. I noticed that one of the males showed some male preflowers in the typical "ball on a stick" form, and some of the other telltale "crab claw" variety. The "claws" are easily mistaken for teardrops when they first show.
