Know before you buy
You should apply PK 13/14 for a single week during the flowering stage. It is best timed when the plant has begun to form flowers, as this is when the demand for phosphorus and potassium is at its peak.
Yes, CANNA PK 13/14 is highly versatile and compatible with soil, coco coir, and all hydroponic systems. Its mineral-based liquid formula is designed to be easily absorbed regardless of your chosen medium.
While you can use PK 13/14 on its own, it is designed to work synergistically with CANNABOOST. Combining the two provides a more comprehensive boost to plant metabolism, which often results in higher quality yields and more robust flower development.
Simply measure the required amount of liquid concentrate and add it directly to your nutrient reservoir. Ensure you mix it thoroughly into your water solution to maintain a consistent nutrient concentration for your plants.
The high concentration of phosphorus and potassium provides the essential building blocks for energy transfer and cell structure during the flowering phase. This helps plants support heavier fruits and flowers while improving overall plant rigidity.
