Gold Label Ultra PK is a flowering additive based on advanced polyphosphates and chelated trace elements.
Ultra PK has been specifically developed to perfectly balance your NPK and micro elements in all stages of vegetative and generative development.

Never combine pure nutrients together, always mix in water. Shake bottles before use, store at room temperature.
