Alien vs triangle f2 Auto (First grow)

I got a couple F2 autos as freebies from SeedsmanSeeds. One is growing tall like a sativa and the other is small like an indica. Around week 5 they started smelling super skunky which I found odd because I was expecting a pungent, piney citrus like some websites say. Kinda got the feeling it got mixed up with their Sour D Haze autos but I don't know. How do yours smell?

First diary but not first grow?

I'm sorry, I thought I mentioned it was also my first grow.
