It's hard to tell a strain from a pic without knowing the parents of the seed. You can tell if it's Indica or Sativa by looking at the leaves. If the leaves are wide it's most likely Indica dominant and if the leaves are thin it's Sativa dominant. The best way you can tell when it's time for harvest is by checking the trichromes. By the sounds of things ya still have atleast another 4 weeks or so before harvesting.
