PH - What am I doing wrong?

Discussion in 'First Time Marijuana Growers' started by The_Green_Goblin, Nov 4, 2014.

  1. My setup:

    Canna Terra Pro
    Dutch Master nutes
    3 point calibrated ph meter with temp adjustment
    6.3-6.5 water
    6.7-6.8 soil
    4.4- 5.2 runoff

    I nute lightly. 1/3 of dosage. Tonight I went 3/4 though as my plants are maturing. Most in flower now. Only nute wvery 3rd water. Flushed about two weeks ago..

    Runoff seems really acidic for the amount of nutes im using..

    Although my new calibrated ph meter has shown my soil ph meter is a little out..not by much though

    Any ideas?

  2. it's near impossible to accurately test the PH of water that came out of a pot of soil..
    are your plants unhealthy?
  3. Nope. They look pretty sexy :p

  4. Maybe something to pay attention to as the few weeks keep rolling in. If plants still look good then the soil is doing it's job to automatically fix the ph.
