Ask a Question
  • What's in it how is it made, I use general organics and they are out of Cal/Mag

    Hey, the Cal-Pow is a Syntheic nutrient.
    Since you are using general organics are you looking
    for an organic version of Cal-Mag?
    if so I would reccomend out Organical Magic product,
    this is a naturally derived Calcium and Magnesium product.
