My well waters test results came in, What does this mean for me and my plants?

I am growing in roots organics 707 soil and use well water to water my plants..ran into some issues and was instructed to find out what the contents of the water are and here they are...results are as following

Free Availible Chlorine: 0 ppm
Water Ph: 7.2
Total Alkalinity: 350ppm
Calcium hardness: 340ppm
Total disolved solids:800ppm
copper/iron:0/0ppm


So what does this mean for my soil indoor grow?

what issues did you have, i have well water too and i use a reverse osmosis for my saltwater set up but tap water for my girls because i figured they would like the calcium and nitrates and theres no chlorine.

Growing 3 plants, 2 are fine, but the one just has random ass necrosis on random ass leaves randomally on the plants.

somtimes you get a bad seed. if it was the water i would think it would effect all the plants
