Ph is going through the roof? What the hey?

Ok then no chlorine there. That wouldn’t have any effect on pH. Dissolved CO2 would though. Still would let water sit and check water temp. I always chill mine to around 65F before using. That should get the CO2 out before you check pH.
You can check your well water for desolated solids, bacteria and other contaminates here.

Damn dude. You know your sh!t. You must grow some primo bud.

Looking at your pictures seems like they have a bit of Claw effect on the leaves. Could be heat/cold stress. Could be nutrients or soil issues.
I’d first check your tent temperatures should be around 75-65 day to night. About 10 degree difference.

I try to keep my temps and humidity within vapor pressure deficit range for plant below.

Doesn’t the water continue to absorb CO2 as long as it’s exposed to it?
And I know too aggressive of an agitation while mixing nutes will also reintroduce CO2 into it.
Does the soil offer any filtration or separation of it like other trace elements?
I’ve never had CO2, or chlorine for that matter, be an issue for me with growing.
The amount of chlorine in the average municipal water system is 60x LOWER than it would have to be to cause plant damage. There are legal limits to the PPM used in systems.
And microbe colonies have been shown to rebound completely in 24 hours or less.
Some microbes will actually consume carbon in the soil. It’s one of the things they get back from the plant in their symbiotic dance.
Oxygen is never a bad thing for the roots.
Organic activity in the soil will send soil Ph up also. There can be too much of a good thing sometimes.

Yes I think the best way is to use reverse osmosis and keep water temperature below 70F. I’m using DWC hydroponics. With soil I’ve heard it is a bit more forgiving. But once soil gets contaminated it’s hard to change out like you can with hydroponics.
I’ve been using beneficial microbes, Hydroguard, to promote colonization of the good microbes. They will help soil too, but I’ve read FF ocean forest has that built into the mix. Not sure if it’s needed.
