as the plant is getting taller,instead of the normal 5 leaf,its starting to grow really big single leaf,will upload a pic tomorrow,any ideas of strain?k2 i was told

Don't know till we see

That can be a sign of stress.

Even with a pic, identification is utterly and compeletly impossible. The most anyone can say is that a plant is either Indica or Sativa. Beyond that, its all just fantasy and fiction. Anyone claiming otherwise should be avoided like a plague of dereks.
