has my plant started budding?

[Th3 sand m4n]

ok, i see preflowers, on every bud, but no white hairs, i see a few white hairs coming from behind a couple of calyx's but that is all(they have been there for about 4 days), it has been on 12/12 for almost 2 weeks now, should i be getting worried, do the preflowers mean it is definately female?

if you see preflowers then you can safely determine the sex. its either got pistils or male flowers heres a pick to help
