Correct ph varying between rapid rooter, rook wool, or not using a medium at all.....

Ok I jus was doing a bit of research and found the correct ph for every medium, but the way my new setup is, I have a clonor bucket and then I will pot my clones strait into, so I'm not using any medium, I have not found an optimume ph for the roots without any medium, u get it I jus transplant my clones into 3 gallon buckets no medium or anything but hydrostone, lol I feel lik I can't explain it smh..... I guess my question is, what is the optimum ph for the roots not the medium (cause I'm not using any)?????

The same - around 5.8 is optimal.

Don't make things to difficult for yourself. Optimal is 5.8 but letting the ph swing between 5.2 and 6.2 is not a bad thing. Nutrients are more readily up taken by our plants at different ph levels, just keep it in that range.
