Measuring PH in water

[Loretta68]

How can I safely raise the Ph in my water (well)?
Before nutes its 7.1
After nutes its 6.1
I've added baking soda a couple time but afraid over time that will hurt my girls.
Can anyone help?
Thank you

General hydroponics makes PH up and down. It's available on amazon and most grow shops. 6.1 is about where you want to be. Let the nutes sit for a bit and it probably will come back up a little.

I just bought a whole bunch of disposable 3 ml Pipettes to measure out ph up and ph down.
I’ve got 300 of them set for awhile now. For like 6 dollars.
I suggest getting ph up and ph down. Not to pricey. Any will do if you search
hydro ph up and down.
