Let's play guess which is which! / What's up with the leaves on one of them?

I have 5 plants about 5 weeks old or so from seed. I figure I've got 3 strains here and 1 is definitely O.G. Kush, 2 are some unknown good stuff, and 2 are from some decent Indica bag seed. I'm guessing the middle one with the leaf problem is the O.G. but I can't tell for sure.
The center plant has some leaf issues which may have been from burning due to a round of spider mites that got stomped out with some organic bug killer about a week ago. (All natural oils; clove, peppermint, etc. etc.) I started giving MC Tomato nutes about 2-3 weeks in at half strength and they reacted very well to them so far. Any input is appreciated. =)

The 2 on the right are what I'm guessing is the unknown good stuff, middle is the O.G. and the other 2, again some unknown indica bag seed lol I'm so ghetto, I love it.

Also, are these too early to top? They are all the same age despite 2 being almost double the size of the smaller ones. =)
