Ummm, Indica or Afghanica, if it goes into flower at 18/6 it has ruderalis traits. Could be a Hybrid, depending on the stretch during flower. Anyways take your pick, it's your special little buddy either way. Really need to know yeild, special trates compared to standard cannabis, and do a smoke report. If you want a prayer at figuring what it may be close to (or maybe is). But the leaves look a little thick for purple haze... Look up Purple Haze on google or wikipedia, it's harder to find than true g13, hence the g13 taken from the goverment was a male...
