Reverse osmosis system
yup, some companies also make nute for hard water.
Right out of the ground let it sit overnight ph is at 5.8 in hydro water ppm is 900
It def shouldnt be that high, I have a well and its about 20 ppm with a ph of 6.3 straight out the tap.. Its nice being able to add water without ph up or downing.
What is your PPM of your plain water ?
Reverse osmosis systems can be more trouble than worth and cause your plant more issues sometimes.
Try fill a tank with plain water and leaving ti to stand for a day or so before using(or even longer) the PPM will lower.
