Purplish hue on leaves?

[Bimmer85]

SO I had another bag seed pop up yesterday and the leaves seem to have a blueish purpleish hue around the edges. Does this mean the entire plant will grow like this or just some deformity? Im actually happy as fuck right now, I love the way purple strains look. Unfortunatly I dont know what strain it is since its seeds my friend got from a grower. Ill post pics once its grows a little since my camera sucks and cant focus in on it that small.

Sometimes they change color during their growth cycle. You can make some strains turn purple by subjecting them to colder temperatures too. Doesn't mean anything as far as potency but they sure look purdy.
