might want to check out the Deep Water Culture forum Under Hydroponics( those guys know they're stuff) I think it is labeled 'DWC/Deep Water Culture. It sounds like you have a nitrogen def (yellow leaves purple stems usually means lack of nitrogen.)
But might just as well be a PH problem, Pic's would be really helpful! Good luck with the problem.
Screwnuts, Roseman,Mostly Crazy,FryinPanFlyer anyone care to venture a guess what his problem is without seeing them?

I guess I was too baked this morning!
Upon further reading it seems that yellow I read was your ph paper color?And not leaf color "using chimicles it was yellow which is..6.0" DUH!!
I still think your problem leans toward the nute def. Can't know for sure without pic's though.
