Green Planet Nutrients PK Spike - 500 ML

GreenPlanet Nutrients PK Spike is a phosphorus and potassium supplement and flowering supplement for the flowering stage, built to support heavy fruiting and bloom development. This liquid fertilizer additive is designed to encourage budding, help facilitate bulking, and support ripening when plants are putting energy into flowers and fruit.

PK Spike is derived from multiple, highly soluble sources of phosphorous and potassium, making it a focused flowering stage additive nutrient rather than an all-purpose base fertilizer. The goal is simple: deliver high amounts of PK to flowering plants so bloom performance stays on track as demand rises through flower formation and finishing.

During the flowering stage, phosphorus is tied to essential plant functions that benefit flower formation, including photosynthesis and energy transfer. PK Spike is positioned to help plants uptake the nutrients essential for budding, keeping bloom development moving without turning your nutrition plan into a long list of separate products.

Potassium support is a core part of what makes this phosphorus and potassium supplement different from a one-note booster. Added potassium helps convert phosphorous into energy the plant can use and helps strengthen cell walls to support heavy flowers. Stronger cell walls are also described as supporting plant health by boosting the plant’s immunity response to pathogens and attacking pests, which matters most when plants are carrying heavy flower sites.

PK Spike is also described as helping tighten up airy and loose flowers that plants lacking in potassium can develop, keeping the finish more solid as flowering progresses. The formula is clearly identified as 0-14-15, so you know you’re choosing a concentrated PK-focused bloom additive rather than a balanced nutrient.

This product is listed for use in hydroponics, drain to waste, recirculating systems, and soil/soilless gardens, making it easy to match to common grow setups while keeping the same bloom-stage purpose. PK Spike is a good fit for growers who want a highly soluble phosphorus and potassium supplement that supports budding, bulking, and ripening, with a clear heavy fruiting focus and a straightforward liquid fertilizer additive format.
