Your total dissolved solids (TDS) out of the tap is 400 ppms. Generally, I don't like using tap above 200, but it depends on what makes up the TDS. If it's mostly Ca and/or Mg, that's good for plants. 100 of yours is sodium, and 150 is chloride, which your plants don't need (at best) and are "using" ppm headroom that could be used for nutrients. If I had your tap water, I'd run it through an RO filter before giving it to my garden. Your question about adding calmag depends on what system you're running. With synthetic nutes in soil, I add calmag to every non-feed watering from the fourth week of seedling through the third week of flower.

That's too much info for me either. What I'd do is like multiple plants in one grow. One with pure tap. One with tap + Calmag. Then another variation (tap + Nutes+calmag?) so that you can just see what the real end result is.

You should be ok. I would get a small carbon filter. You can get one for a rv that goes on the water hose. It will help reduce the chlorine in the water.

I'm using soil and so do I just buy an ro cleaner or wtv I just don't want to use ro water bc it would cost like $100 a month if not more and I am using synthetic nutes
Is the ro cleaner a fish bubbler or like a thing I attach to my faucet ?

I use a small RO system. It's the Geekpure 3 Stage 100 gallon/day...available on Amazon.

I'm growing indoors what would help for indoors? I don't use a hose to feed

Hose filters like a C-85 inline hose filter, will remove about half the PPM.

A true 3 stage RO system will have zero everything and should be sterile for the most part.

I use a Zero Water pitcher to filter my water.
Before the pitcher I used a faucet filter made by a company called TappWater.
