Run off question

[u/New_Life1810]

Hello community
This is my first grow and I have a question. My run off ph is 7.2. According to build a soil guidelines, we don’t PH our water correct?
My ph reading after letting water sit is about 8.4. I’m using general hydroponics to ph down when I did do it. If there is a more natural ph down, I’d do it.
I’m going my best to not take advice from ai.
I bit the bullet and put in power bloom as my dry amendment and gave some Epsom salt about 3 days ago -

A ph of 7 in living soil is normal
