PH questions

Discussion in 'Growing Marijuana Indoors' started by indoor newbie, Jan 21, 2010.

  1. I have a couple of feminized white widow seedlings going in 6" pots under a CFL array, but they're coming slowly. I've trouble-shot light and heat issues and aerated the soil a bit more, and the last go-round in this forum suggested maybe some PH issues. I have one that's in the low 6s, and one that's right around 7, so I'm wondering what I may need to do to tweak the both of them nearer to that magic 6.5. Any thoughts...?
     
  2. I use PH buffer solutions. PH up and PH down so you can adjust to the magic 6.5.

    You say 1 plant at low ph6, and one at ph7...those were runoff measurements?

    So basically you want to give your ph6 plant around ph7 water, and ph6 water for the ph7 plant. Your just countering your runoff with the PH of the water that goes in.

    Hope that helps.
