How much of a problem is minerals in your RDWC system? Pure groundwater, no chlorine or other treatments.
My goal is OFC to have as healthy plants as possible. But at the same time extend water changes as much as possible whitout putting plants at risk.

Water test do i need to treat this tap water

You have E-Coli in the water, thats highly unsafe even if in small quantities. Do you have animals nearby? Usually its fecal matter filtering through the soil what introduces E-Coli in the water. For watering plants seems okayish but I would add a dash of hydrogen peroxide to get rid of all the stuff in there and let the water sit for 1 day or a few hours so the hydrogen peroxide has time to degrade too into oxygen and water, just because that water coming into contact with your hands is dangerous. You can touch your eyes, mouth or whatever and get an infection.

6 water hardness is entering the hard water zone so I would basically watch out to not use too much calmag if any at all, depends on the size of the plants.

I do not have E.coli. They tested for it and found less than 1. Which is completely normal in "real" untreated water. The company who done the test explains that <1 means it was not found in the sample.

Not that I advocate for a second that you trust your government, but most municipal water providers in the United States test and treat drinking water to meet very stringent ANSI standards. In most instances municipal water is fine for agricultural irrigation but it might not be suitable for hydroponics right out of the tap because of the minerals, chlorine and chloramines. But that's not my forte, I'm a lazy dirt guy. I tip my hat to you folks with the patience to keep a slime free reservoir. 😉

You need to purify the water, as if nothing is more important, and then add minerals, as if chemistry is your middle name. How else? It's hemp, a weed that loves you more than anyone else🤣
