Hi Keiley 35,
No hairs yet is odd but from the pix they look fine, I think you're just way early. Looks like they might be a full on Sativa which could take 11 - 13 weeks.
From my exp. with the Cheese I think it's mostly Indica but man they sure look & act like Sativa sometimes.
Lastly, and hate to even bring it up, but..........the seeds are in question, you are noticing something different & large early cluster formation with no hair. Might bone up on hemies, just so you know what to look for.
I see nothing in the pix so don't panic, just thinking out loud.
