Could this be an Auto

[Bimmer85]

This plant is about 3 weeks old but is starting to show pistils. It is also significantly smaller then one of my others which was planted the same time. Can this be an auto since its only 3 weeks and so small in size yet already showing pistils? Here are pics of both for comparison of the size difference.

Too young to really tell at this point and it doesn't really matter anyways. If its an auto it will just finish sooner.
