Best PH for soil feeds

Discussion in 'Growing Marijuana Indoors' started by Kali King, May 10, 2011.

  1. What is the best PH the water/feeds should be going into the soil? Does it change for an outdoor soil plant?
  2. Depending on the substrate, pot plants need a pH of 5.8-6.5. This rule doesn't change with where the plants are grown, but the best pH within that range can. So, the pH can be different for an outdoor plant but not necessarily.
  3. I've been giving them 6.5, I'm dropping that now to 6.0-6.3 now thanks.
