Lookin Healthy?

I have a few babies started a month and 1 week ago at my buddies house. First time start growing. Just wondering if they growing at a healthy rate and if there's anything wrong with them. I am cultivating them inside in a well ventilated place using (3) 42w fluorescent light bulbs and a normal 23w fluorescent. Only growing them to about 22".





Some leaves are starting to grow in more skinny now and kinda concave. Is that natural?

On pretty much on all of them, the first 2 leaves have died which hasn't been a problem, but now on one of my plants the second pair of leaves that grew are now dying. The rest of the leaves are fine and don't show any signs of doing this. The leaf on the right is yellowed. reasons? How to fix?

They are good for just a couple of cfls.

I think those look pretty damn good for a first time effort under cfl! More light more growth, you know? Rest of the plant looks pretty green? Right? 3rd set still real green? I wouldn't worry about those lower leaves. Do you know what strain at all? What nutes?

Used a mixture of topsoil and expensive fertilizer with self releasing nutrients haven't added any manually yet. Those are just 4 out of 6 I have, all of the ones in the picture are some type of pk and other kush seeds all indica, that I've collected from buds myself. 3rd set of leaves doing fine.

The only thing that concerns me still is the leaves that start to grow in now are more thin and concave like you can see in the close up picture. Is that bad or is it just a normal change in growth that happens for some reason.
