Need some advice on what the issue could be, ive done a reading up on what it could be but i would just like to get some clarifications.

Plants are under 4 150w CFL's, and 1 100w CFL for the Vegging process, will switch to 250 hps a little further into the vegging process.

I havnt started adding nutrients yet, i have the Fox Farms Trio Pack, when should i start using that?

Plant A Showing very slight yellowing on bottom leaves

Plant B Showing Exteme Case Of yellowing and dieing leaves

Plant C Is Showing Really Pale Greenish Yellow leaves

And Plant D just looks plane old retarded or something (sorry the pics kinda blurry)

Check your ph. I bet your soil is too acidic.

n.p.k is not really ideal for vegg.
you want something high in nitro.

Any suggestions on what might be a good nutrient brand for vegging then?

Okay ill pull the lights back alittle, should have figured cause plant A is the furthest from the light and its doing the best.

3 of the plants are set up on wick systems and the other two i water about every 2 to 3 days, just whenever the medium is dry a couple inches into the container

Lol. Best answer yet. Almost like from the hangover uncut verison. "I really dont like your language. There are little kids here!" "Yes"

And yeah you need something with more nitrogen and back off the lights slightly. How big of pots do you have them in right now?
