Hesi PK 13/14 is a PK (Phosphorus and Potassium) booster for specially formulated for use with plants growing in hydroponics systems or coco coir. Plants need a lot more phosphorus and potassium in the flowering phase, by applying PK 13/14 growers can completely fulfil this need. The flowering phase is the supreme point in the life of the plant. The metabolism is then working at full power and large quantities of enzymes are in production for flowering. Furthermore, the plant gets bigger and therefore needs more components. The specific substances that are responsible for this are phosphorus and potassium .
To ensure that the plant is not bogged down unnecessarily with ballast or an excess of salt too early, apply Hesi PK 13/14 from the second half of the flowering phase up to one week before the end of the cycle. The dosage gets slightly stronger over the final weeks of the flowering phase.
Hesi PK 13/14 is best in conjunction with Hesi Hydro Bloom (if growing in a hydroponics system) or Hesi Coco (if growing in coco coir). The composition is 9% Phosphorus (P) and 7.2% Potassium (K)
Using Hesi PK 13/14
At Canterbury Hydroponics, we always suggest following the manufacturers grow schedule. If anyone knows how best to use their products, it’s them! This will ensure your plants get all the nutrition they need, right when they need it. Your plants will get a boost to their maximum potential and more likely to deliver a satisfying harvest. Never mix nutrient concentrate in neat form. They could react badly and adversely affect your plants. Elements can bind together and become unavailable for absorption. This can easily result in malnutrition and the need to take corrective measures.
