I see a good strong, healthy Sativa there, bet if you keep up at this rate your gonna have some great smoke curing in no time at all. MMMmmm I can just about smell and taste it now.
Good Luck and please do keep us up to date won't you ?
There is no way to tell strain. Your plant does look sativa dominant, however, so you are probably looking at a 10-14 week flowering period. Try and be patient, your girl has quite a ways to go.
