    Jacks 321 vs Masterblend/Calnit/Epsom salt analysis

    Any chance someone can help me figure out why I am getting a Potassium Defiency exactly at 2 weeks after the switch to Flowering Light cycle? I am tempted to try the Jacks cannabis Schedule of 10-30-20 for the one week without any Calcium although it seems counter-intuitive. Just wondering if I...

    Jacks 321 vs Masterblend/Calnit/Epsom salt analysis

    Anyone else realize that the 3-2-1 is really closer to a 3-2-.5 than a true 3-2-1? I think I calculated 3-2-.64 approx? Don't you think a 3-2-1 is too much Magnesium especially if topping up on a recirculating system??

    Anyone here really good with numbers I am trying to compare Jacks AN and GH...

    This is what AN sent me I didn't realize maybe it was on the label? Specifically I am curious about the amount of Calcium Magnesium (and ratio to K) including 3-2-1 and without the 1 (3-2) Mag. And GH with R.O. Water using Cal/Mag. By the way 3-2-1 is really supposed to be 3-2-.6 . Not sure...
