Grow Mediums NEWB nute question

[devils lettuce]

Nothing if you can keep it stable. The problem with the pH Perfect was it was all over the place day to day and the plants were really suffering. Soon as I switched to the House and Garden Aqua flakes that all went away, the pH stabilized and the plants responded.

seems like to much bs to worry about.. my waters ppm comes out of the tap at 11ppm . it would be nice if it did work .
