I put my 3 inch cubes in ph 5.5 water with air and water pumps on and after checking the ph again it's has risen already to 6.1 should I leave it or adjust it?
Thanks

You soak with acidic water to break down the glue they use. Its normal for the ph to rise a bit as this process is taking place.

That's the thing with rockwool, I use it too and no mattter how many times I adjust the ph it keeps rising. As long as you keep track of the ph during growth you should be OK. As for the cubes, once I soak it in proper ph I don't bother with it 'till I plant it in my final medium.

6.1 is fine to transplant in!
