First grow Plant problems

So I have 3 small clones. 2 of them are starting to get purple stalks and stems. The purple goes in a vertical line up the plant. Also, One of the plants, I can't tell if I'm under watering or over watering it because the leaves are sagging, but its still growing. The other 2 plants look fine. I'm using my own soil with some organic 5-5-5 fertilizer. I'm watering every 3 days about a water bottle full for the 3 plants.

Raise the light like 4 inches....thats really close! also they dont look to bad.

How old are they? I think they look decent also, depending on age.

I bought them 9 days ago. they came in a foamy sponge like cube. when I replanted them 4 days ago i noticed the roots already grew 2 or 3 inches into the soil. The lights are only 23 watts and they all pretty much an inch away. I guess I'll raise 'em a little.

If you have a constant flow of air from a fan you can get as close as an inch easy but a couple inches is safe. Add more CFL's if you can.
