My pick is most likely hybrid. My reasoning includes:

-Commercial bagseed is commonly hybrid, and as I recall HC is growing bagseed.
-Hybrids may have extreme wide leaves; see Greg Green's Cannabis Breeder's Bible.
-True Affies have a long slender tip on the leaves, whcih are wide but not excessively so.

I've never seen an Afghan that looks like that, and I've never met anyone who can determine lineage from a picture of a 3-node seedling.

C. indica var. Afghanica is a subspecies of C. indica, not a species in its own right. And pure landrace Afghani is not as easy to find as one might suspect.

This whole thread is speculation.
