Pre-Flower At Only 3 Weeks???

Not only one, but two different phenos are pre-flowering at only about week 3. Both girls too! No question about it, btw. The classic intertwined, silvery strands of glistening hair. One is a Top 44 Indica, the other is unknown and quite exciting bagseed. Big ass leaves already, lots of red in the leaves and new shoots, twice as tall as the indica, some sort of Sativa.

Isn't that strange that both are showing female sex so quickly? I've got them cloned to check sex on them and the clones haven't even started thinking about roots yet?

I've got 5 gals out of ten so far, btw, the others are still unknown.
I'm hoping for 2 more.

Any risk that such early pre-flowering indicates hermies?

not really any indication of them being hermie some strains will preflower at about 3 weeks but most will take a little longer.
