What pH is best for flowering?

A pH of 6.5 is just about right for most home gardens, since most plants thrive in the 6.0 to 7.0 (slightly acidic to neutral) range. Some plants (blueberries, azaleas) prefer more acidic soil, while a few (ferns, asparagus) do best in soil that is neutral to slightly alkaline.

What causes pH to rise in coco?

Most of the nutrients you’ll use for growing cannabis are slightly acidic. Which means a reservoir is also an acidic place. As plants absorb nutrients, they will also absorb some of this acidity. Gradually, you’ll find the pH levels rise as the reservoir becomes more basic.
