Ok so I've been using RO water and AN ph perfect part A and B growing in soil. After I mix the nutes up, the ph always settles at 5.7 or 5.8. Just out of curiosity, I mixed them with straight tap water and it settles at 6.3-6.5, which I assume is better seen as I'm using soil. Should I switch to tap water half way through my grow??? At least the tap water would contain some Ca and Mg right?
Here's a link to my grow. And to clarify. It's not actually RO water, but it is 0PPM.
