We're finding out that TDS matters less than what those dissolved solids are. My tap water is 100 to 110 ppm TDS, and I water most of my plants straight from the hose. Check you local municipalities water quality report to see what your water has.
Mine tests for trace metals and chemical runoff, but only finds a few metals measured in ppb (parts per billion). For other stuff that we know are not good, I have .19 ppm copper, 8 ppm sodium, 2 ppm nitrates, and no calcium.
Everything happens for a reason. Sometimes the reason is that I make bad decisions.
