In the MVP’s operational documentation, I’m confused about the PH and the PPM levels. There doesn’t seem to be any numbers specified.
For example, here its says “Check your source water PPM count with sensor”, but what level am I looking for?
And for the ph, what level am I looking for? How do I adjust it? The slides only say to check the ph without instructions on what to check for.
More details would be appreciated, I’ve barely grown anything, let alone hydroponically, so I need some hand-holding!
