Help: Yellow, Purple, Droop?(Pics)

This is my first grow and I'm running in to a few problems. They are growing pretty well I believe for 2 weeks, at least most of them. But My best one is having some trouble with the lower leafs turning yellow. I thought that it was because a lack of light so I moved the lights closer. Temps are in the low 80s usually. Lights are on the side of the plants. (26watt CFLs, 4' tubes overhead)

Whats wrong with my girl?

Also, some of my other plants have purple stems and are drooping. I was told it was a watering issue, but my watering has been under control lately and I'm seeing no improvement. I have a moisture meter, I wait till they are n't heavy, and dry a good distance down. Then I water lightly which usually lasts 3 days. I figure they might be lacking some nutes. I really havn't given them much and there pH isn't really under controll.(I just started fixing the pH which was a bit acidic. I tend to just give a few drops of organic fert 5-3-4 in their water because they were young, is it time to up it?) They are all about 2 weeks old, if even.

Could the pH/nutes be the problem for all of this? Am I over/under watering? Lacking Light? Do I need bigger pots?

Any help is appreciated.

(P.S.- Some of the plants have a very... crispy feel to them. I'm starting to think I'm under watering.... I'm at a loss.)

I'll probably be giving most of them new 3 gal pots tomorrow. So just super water the crap out of them, then transfer them in to the new pots?(With new soil that will be adjusted correctly) The new soil contains timed release fert that I havn't decided if I wanted to flush completely of flush most and give a layer of non-flushed on the top to give it some nutes.
