Indoor Different Pheno or Strain?

[vv15629]

Sup guys! Been out of the grow scene for a couple yrs now just getting back. Anyway, I've got 3 Candy Kush autos at close to 6 weeks in. So two of them (right and middle) are growing very similarly. Relatively tight, not a lot of long reaching offshoots. The one on the left however is overall bigger and bushier with a lot of reaching offshoots. Just a Different pheno or possibly a different strain and the seed was mislabeled?

I've had several grows with the same strain side by side and one grows tall, the other fat and short. Just never know for sure what will happen.

I guess that could be the case
