Ro water vs natural spring water

[Reid77]

Having issues with water I grow in dwc single buckets. My tap ppm is 330-340 which is high. I have access to natural spring water (free) or buy bottles of ro water. Spring water is around 260ppm. So wondering what I use spring water or the ro which then I would also need to buy calmag. Thanks for any tips or help.

Mix them 50/50. You end up with about 150- 175ppm depending on the ro ppms and no need for cal mag.

1 bottle of ro was like 6 ppm the other was 12
