flowering question

[fhydro]

Hello, i've got a bubbler system with different strains going on. I put on 12/12 5 weeks ago, and i notice that the more sativas phenotypes are flowering more quickly than the more indicas phenos. The first have got beautiful white hair flowers and the other are just starting showing the pistils. I already remove the males. The slowest to flower are from female seeds, all females, but with very thick leaves. Any exponation ?
Thanks

i dont wanna adventure myself in this subject too much coz im not really sure, but id say indicas are smallest, but they may take a bit more time to flower, at the inverse of fast and tall sativas.
