Mutant Plants?

So I decided to try and grow a few plants. The first and bushier one is about two weeks old from random bag seed... looking kinda droopy. The second which also comes from the same random bag seed has two regular leaves, which in my opinion is a little funky.
The third is a seedling which comes from an O of beasters that only had 5 seeds. As you can see it has 3 leafs instead of the customary two. What do you guys think? This is my first attempt at growing anything.

the drooping in the first pic looks like overwatering maybe? the second(mutant) looks like it just has 3 cotyledons and they will end up dying and falling off sooner or later...

they dont look like mutants

yeah its nothing to out of the ordinary or mutant. just rare like a 4 leaf clover kinda deal

Thanks for the reply guys. Here's an update on the plants along with the setup I got going.. please don't laugh. The first three pics coincide with the same plants in the original post and the last pic is just a third plant which I felt looked the most normal so I didn't post.

In the second pic, the bottom leaves are dying and turning yellow which I believe is from over-watering, but I'm not entirely sure. Two of the plants have a problem with the leaves curling, which you can kind of see in the last pic on its very far left leaf. Not sure what the deal is there. Slight over-watering maybe? The leafs on the plants are also a very dark green color, much darker than I would have expected before growing. Other than that I think things are going great so far.

Tomorrow I'm thinking of going out and getting some basic nutes from ACE Hardware with a high N content. I read that the sex of the plant is determined in the 3rd - 4rth weeks and that an increase in Nitrogen will increase the chances of a female plant.

why are your plants growing so slow

They're growing slow?!?! Man... I was thinking they were doing pretty good. Like I said its my first grow and I think I over-watered them and possibly stunted their growth. They also might need some more lights. I currently have 4 x 23w 6000k and 2 x 23w 2700k to even out the spectrum a bit. Any advice would be appreciated.

you might want to step up to a HID. florescent just dont release enough energy for fast growth
