Did you soak your rockwool for a day, prior to using them?

pH the water to your desired level, then add the nutes.

Earth Juice brand ferts will almost always drop the pH initially. Silicate-based products often raise pH. Some folks bubble their nutes for 24 hours to stabilize em/monitor what they will do before adding em into their res.

So many combos are possible that you just have to tweek it/play with it until you find that sweet spot. If you can't tame the beast, you will want to add nutes in and wait/take readings after each addition until you find the component in your mix that's making the pH rise.
