Pretty interesting indeed seeing the two vastly different phenotypes. The one on the left looks suspiciously much like a GrandDaddy Purple Auto which I've grown this season outdoors. Especially because of the shape of, and the colouration on the leaves. GDP Auto is a strain that is sold by Royal Queen Seeds too, so perhaps it got mixed up somewhere? Otherwise, you'd only see this expression if a pheno was kept too cold - but I assume both were raised in the same spot.

Looking great! Especially appreciate the trio-picture of with the Z-up next to it, gives a good sense of the size of the plants. Are you planning on harvesting around the suggested 10 weeks or are you planning on something else?
