More info is needed on your set-up. Like what medium are you using? Rocks? What nutes? How old are the girlies? The ph rising could mean a couple things. It could mean your girls need stronger nutes as they are drinking the low ph nutes and leaving just the higher ph water. The white stuff on your rocks could be a salt build-up which could mean you need to flush them with a clearing product such as Florakleen, which is what I use.

what kind of numbers are we talking about? if you have too many plants feeding from the same rez, you're gonna have wild ph swings.

the white residue is more than likely salt build up. (or cocaine) lol
