Why is one smelling and one not? Same strain.

I have two plants that I'm growing as a trial run kind of thing. Both planted from same bag seed and a couple weeks behind because of how I started them. Anyway, they've really picked up and caught up. I have noticed though that one is a little bigger and stockier than the other and that one is really starting to get pungent while the other has no odor at all. Any guesses or comments?

Some plants smell and some don't. That's all there is to it really.

even though they are the same seeds ie: from the same 2 white widows could smell completely different because there are different phenotypes within the same type of plant.

Thanks for the answers guys. I was just wondering if it might be an indicator of something.
Hogg; is that true if both seeds came from the same plant?
