PK Spike is our flowering supplement derived from multiple, highly soluble sources of phosphorous and potassium. This product is designed to encourage budding, help facilitate bulking, and ripening of flowering plants.
PK Spike is derived from several highly soluble sources of phosphorus (P) and potassium (K) to deliver high amounts of PK to flowering plants.
During the flowering stage, phosphorous plays a key role in the essential functions of the plant that benefit flower formation. It helps the plant perform photosynthesis, transfer energy, and easily uptake the nutrients essential for budding. Added potassium helps convert phosphorous into energy that your plant can use and strengthens cell walls to support heavy flowers. Stronger cell walls support plant health by boosting the plant’s immunity response to pathogens and attacking pests.
Potassium is also responsible for tightening up airy and loose flowers that plants lacking in K develop. The result is a healthy plant that will produce your heaviest yields yet.
Add at a rate of 0.5 – 1 ml/L to your reservoir.
Apply from the 2nd week of bloom every 2 weeks until 1 week before flush. Applying PK Spike at the recommended rate will deliver up to a 250 PPM boost to your plants, adjust your nutrient strength accordingly.
