Gold Label’s Ultra PK is a flowering additive based on advanced polyphosphates and chelated trace elements. The flowering additive has been specially developed to perfectly balance your NPK and micro elements in all stages of vegetative generative development. It prevents phosphorus from depositing at pH levels>6.2, promotes availability of Ca, Mg and trace elements and keeps your drip lines clean. It’s able to be used with all other Gold Label Base Nutrients. Also, customers should never combine pure nutrients together and always include water to mix with and shake the bottles before use and store at room temperature.
Phosphate P (P2O5): 12%
