pH rising from airstone

Cannot seem to find any posts on this issue , the ones I do find do not seem to have a solution.

I am running a waterfarm which has a 4 gallon res with an air stone along with a air lift top fed spraying system.

I let my water stand for 48 hours then adjust pH down to approx 5.5 - 5.7 I then add this to the WF - after a day the pH rises to 6.5 - 7 (no plants in the system, no clay pebbles etc) just a clean system. The bucket I mixed the nutrients in has not changed in pH at all and remains...

How to correct Rising pH/PPM runoff

Okay so this is my first run with Hydroponics. I have been running a top feed drip line system. I am running my girls in 6 inch rockwool cubes placed in 7 x 7 pots filled with hydroton. There almost 28 days into veg from seed. I've begun to notice a couple rust spots on my girls nothing too major. I figured starting a little nute burn. So I backed off the nutes a little. I've been keeping track of the runoff and two of my girls now" the ones that are showing the rust spots and a slight droop...
