  1. As the title suggests, do you guys have input on this? Since i remembered i have a bottle of ph down in the closet ment for flowering, that contains 59% phosphoric acid... I was using the vegging PH down from Hesi, labeld (PH DOWN VEG) that contains 39% Nitric acid.

    I'm at week 4 flower now no side effects i only noticed that my leaves are greener, XD..

    I'm actually thinking not to use the phosphoric acid unless some of you come with a reason i should not..
    I'm interested in seing your advice, and comments.
     
  2. Tried the Phosphoric acid, and noticed yellowing in leaves, very interesting... I switched to the Nitric acid and i'm going to switch to phosphoric at the last 3 weeks of flower.
     
  3. Both have their place..
     
  4. Yea, thats what we all can agree on. But i'm more interested in expierances.
     
  5. I use food grade acid powder that brewers and distillers use for making alcohol and my girls are happy. very close to harvest. I'm stoked.
