No clue whats going on with these

here are some pics of the problem plants. I've got 6 going, and these 3 are my main problems and I'm a new at this so I'm clueless on what it could be.
I'm using:
Miracle Grow Moisture Control
7 CFL's, a mixture of daylight and soft(getting more soon)
fan on outside of room blowing in ventilation for air flow(its too strong to go in there)
the room is holding perfectly at 80degrees
I've included a room picture, the lights have moved since then but you get the idea from this shot.

My other 3 plants not shown, the 1 is growing like crazy and looking strong, but the first bottom fan leaves have some brown on the edges. I'm not too worried because its growing well, but should I worry?

The 3 shown in pics, the one is just really skinny for some reason and it's getting the same light as the other bushier ones next to it.

The one sprouted a 2nd stem right after the 1st one from one seed and ever since going in to bigger pots it's been struggling badly(droopy, not really growing) and the bottom 2 leaves, not the fans but the others below have turned yellowish

The other is growing a little slower than my main plant and the one leaf is curling a bit. He's still making progress but i want to cut off any problems if I can.

If it's bag seed you can't expect everyone to be the same genetically. They may get traits from their grandparents. I would'nt stress so much. They all look pretty good to me. If you look around through the posts you willl see plants alot worse than yours. Lighten up and let them grow.....

you are wasting to much of the cfl light. right now the cfls above your plants are emitting a huge majority of light out to the left and right, but your plants r down. you need to rotate the bulbs differently. You will see a difference in light coverage instantly. Also the two metal reading type lamps are really not much help either because again the light is being emitted left and right nstead of down. I mean you r getting light, just about 25 percent of what it could be. I also hope they r 6500k at least 26watt. Play around with the light angles alittle and you will be very suprised.

thanks for the help guys. I'm just paranoid since its my first grow ya know? oh, they aren't bag seed though, they're all white widow but I guess you're right, each plant will be a little different regardless. i adjusted the lights to make them sideways and i plan on adding 4-6 more to the mix to help out on top anyway.

Use some mylar above the lights to get the reflection back toward the plants.

try making a reflector with mylar to control ur wasted light, and for your yellowish or brown leafs try triming it off but only the dead plant material so do it as little as possible this will keep it from spreading. Good luck

Miracle grow soil has been known to burn plants for some...I found it stayed to moist for my likings....adding perlite is always a good thing for added aeration...
