Humboldt OG Kush with rounder leaf

[Treevly]

I grew a number of Humboldt OG Kush and they were quite consistant in appearance - except one, which had notably rounder leaves. It also
had a slightly different, and pleasant, odor. I'm wondering of that plant was reverting back to one if its ancestors, and which one?
What do you think?

Maybe it would help if you post a picture.

OG Kush is originally from a bagseed and its ancestors are not known.

But because of the round leaves let's guess Northern Lights (Afghani).
