Whats wrong with my plants?????????

Hey, i planted 3 seeds about 2 weeks ago all together. They sprouted and grew to about 4-5 inches or so before i seperated them. its been about a week since i seperated them and they are doing fine. As you can see in the pics towards the top there is some purplish coloring towards the top and it extends onto the little stems. They look pretty good to me but this IS my first grow so im no pro . I posted a forum earlier and got tons of help so i hope the same will happen . Also.....i read online that they were supposed to be relatively oderless untill they flower but these have a strong dank-ish oder! .....is that normal? Also....not all three of them have this...only 2..the one close up is the worst the other is less. SRY FOR THE CRAPPY IMAGE QUALITY...hehe

Your plants look fine dude. They look a little streached, but thats ok. Try moving your light closer so they dont have to reach for it.
My plants are in vegg and they smell oh so good!!
