PK 13/14 is a mineral additive based on highly soluble phosphorus and potassium, developed by Canna to enhance flowering. It improves flower formation, increases density, and stimulates the production of sugars and essential oils.
It should be used for only 1 week during the intermediate flowering stage, when the plant has the highest demand for phosphorus and potassium. Follow the Canna feeding chart for precise application.
Compatible with soil, coco, and hydroponic substrates. Its high purity ensures fast absorption without residues.
