A flowering additive that supercharges flower production. Based on advanced polyphosphates and chelated trace elements, Gold Label Ultra PK has been specifically developed to perfectly balance NPK and trace elements. The advanced formula prevents phosphorus depositing at pH levels >6.2, promoting availability of Ca, Mg and trace elements, whilst keeping drip lines clean.

  • Supercharged PK uptake across a wide range of pH
  • Enhances absorption of Calcium, Magnesium and microelements
  • Results in steady growth and heavy flowering throughout the generative phase
