pH rising.

Ok, running an aero system my pH keeps rising. I know that as plants eat nutes pH will go up, but not this fast. Plus she's not even sprouted yet. I've noticed condensation in my airline and thinking this is the culprit. Gonna install a water separator, and hope that works.
Anyone else had this problem?
Of so, what was the cause/fix?

What is your water source?

My water source is ro water. Ppm and ec at 0. Nothing else in the system except condensation in air line.
Perhaps some Rockwool particles. But I don't think that would raise pH so fast.
To be more clear I get my water at save a lot. Grocery store in my area. But it always test at 0 every time.. that's why I use it. No additives.
