2 Hybrids: One looks more Sativa, the other Indica

Hey yall, I'am in week 5 of flowering my ladies and they look pretty good. They're bagseed which is the main concern here. No idea what strain they are. All I know is that they are hybrids. One of them looks more sativa, but the other looks more Indica.

So the question is, Just because one of them appears more sativa does this affect the flowering period length, or can they be harvested at the same time?
