i would start with your pH.
what is the pH of your water?
what is the pH of your runoff??
start there, then when you get your pH stabilized, wait about a week for signs of recovery/deficiency.
more info would help diagnose your troubles.
what kind of soil?
how much and what have they been fed? how often?

Im leaning more towards a mag def. Notice how the chlorosis starts from the leaf tips going inward.
The affected leaves and stem coloring looks too light to be a Phosphorus def IMO
EDIT:
Oh yeah,....Definately not a calcium def, as the new growth looks good. More than likely its a Ph issue.
Check the pH and let us know

Thanks for the posts everyone.
I will pick up some Calmax and a ph tester tommorrow.
Cab: 30x20x72 - LxWxH
Light: 400W HPS
Fan: 6" Vortex, 4" muffin
Soil: promix, perlite, vercumulite.
Temps: 75-80*F
The first picture of my one (sick?) sour bubble.
The second is of one of the plants that hasnt shown the first problem.
The last pic is a leaf, of the problem with most of them.

I bought some pH UP and watered them today with some adjusted water.
The runoff is now between 6.5 and 7.0.
To make things worse, the clones I was given have a couple spider mites.
I moved them to the corner of the room, put up some sticky strips and sprayed everything with neem oil.
Should I wait until I get this problem fixed before I transplant?
Thanks

Your leaves look like they're suffering from hard water damage. Tap water is not the best source of hydration for a cannabis plant unless you're using a RO (Reverse Osmosis) filter.

Good luck and stay green!

Just to be a pain in the ass.. lol.. To me.. it looks like neem burn. I did this myself not to long ago and when he said clones and mites I put 2 and 2 together and got.. The guy that gave him the clones sprayed the hell out of them or did a neem dunk just before he have them to him. It takes a few days for it to show up. The leaves from the tip turn dark green and crisp. I could be wrong..

Ive had the problem for atleast 2 weeks prior to recieving the clones.
Thanks though.
My buddy sprays them with 1/3 ISO 2/3 water to kill the mites. Anyone ever tried this?
Sounds like it could be hard water...
I am going to wait a few days until I get my pH stabalized before I try anything else.
[edit] I am using the same soil for all my plants. The fiesta mix showed this problem about 2 weeks before the sour bubbles, any idea why?
