Sativas generally take at least 10 to 12 weeks, you still got some time to go, they look nice, next time try to take pics without hps on it's hard to judge.
yeah 6 of mine sprouted and the rest im saving. i tried all 12 and 6 sprouted 1 died, 3 went hermy and now im left with too becuase 6 others didnt sprout.
