RO'd minimum, distilled is better. With typical RO home unit, it produces about 2.5 gallons a day, so must capture late every day, and store, or get separate one just for grow. Ours is 265 PPM and 7.6, and I will not drink it. RO's it 16 PPM and 5.8 PH.
RO'd minimum is my opinion, from experience. It is open to debate. Have had numerous water problems, and using RO'd water, with great fertilizer, and organic tea, water has been perfect.
GOOD LUCK!!!!
