Newbie help, have a yellow clone

This is my first grow. I picked up some clones and noticed that this one was pretty yellow. It wasn't a concern until i started reading more about plant problems.

Can someone help me diagnose this problem correctly and also give instructions on how to correct it?

I'm running a hydroponic drip system with 4 40w flourescents. I check the Ph balances daily

Here is a quick view of the set up.


Here is a view of the problem child.

Also the other plants that i have do not seem to have this problem.

I read that this may be a Sulfur problem on another growing site. It said to add 1 tsp of epsom salt to every gallon of water. The funny thing is it sounded like that it was more for a soil based grow. If i add the epsom salt into the mix and my other plants are green will that create problems with the other plants?

Are the damaged leaves the ones that were on the clone before it rooted? If so its normal dont worry about them.

The clone was yellow when i got it. I'm assuming that it was a yellow leaf that was cut.

It means the roots are growing...it's a good thing...
