Will I have pH issues?

[SHRED]

5 gallon Root Trapper II containers.

3 parts Mother Earth Groundswell soil.
1 part earth worm casings.
1/2 part xlrg perlite or hydroton.
A small area with Light Warrior for seed sprouting area of the container.

My home RO water is at 7.0 pH.

I will use the Roots Organics Uprising dry nutes as a top dressing. Maybe some Mykos also.

Will I have pH issues for my auto grow?
I have been informed that RO water doesn't hold its pH once treated.

About all I know is that organic soil will usually buffer the ph instability of your water.

Do you have an additive/base nute or like product to mix with your RO water to ph? Filtered/RO/Distilled water all need some kind of an additive to ph.
