Last time i checked my tap it was over 300ppm and i use it all the time no issues. I assume most is chlorine and calcium.

250 well water in soil sounds pretty good to me. I'd use it.

Im thinking about switching to my well which sits at over 400 ppm...my outdoor I had loved it, only used it once indoor but got good response

Is there a report on what is in the water? If you have a lot of calcium in it, you could run into calcium-caused lockout, especially in flower.

Yeah just depends on what represents that 250ppm.
If it was tap, I'd bet on nitrates but with well water, good chance it's calcium.

My tap water is only 120ppm but there's something in it plants hate even with dechlorination so I do RO it and that makes my plants happy

Should be fine in my opinion but having it tested is really the only way to know , no cal mag needed ! Lol I’d use it and see the results
