I use filtered tap water. The pH ranges from 6.7 to 7.2 and the tds is always around 120 right out of the tap, and that's mostly cal/mag. I haven't used RO water since i switched from hydro, so I have no idea how it would be.I know this is an old post but that “no ph” bit is for dechlorinated tap water that runs a lot higher PH than RO water. General Organics has also specifically told me per email to still check PH after adding nutrients. Just some knowledge for anyone seeing this thread.
