Hi Disturbed_Freak,
Judging by the rest of the leaves in your picture the plant seems to be very happy. since this leaf only has 3 blades, I am assuming it is early growth from a new node. If this leaf was grown while the plant had just suffered a transplant or cloning than that is the reason for the imperfections. If not, maybe it was just a little deficiency early on before the nute schedule was really ramped up. All in all, nothing to be worried about
