Hesi PK 13/14 500 ml – phosphorus-potassium fertilizer for the second half of flowering

PK 13/14 by Hesi is a liquid phosphorus-potassium supplement for flowering and fruiting plants grown in hydroponic systems and coco coir. During flowering, plants need significantly more phosphorus and potassium than during the growth phase, and this product helps replenish both elements precisely when the demand for them increases.

Flowering is a period of very intensive activity for a plant: its metabolism accelerates, large amounts of enzymes are produced, and the plant itself increases in size. Phosphorus is needed at this stage, among other things, to build enzymes and genetic material, and it also supports the ripening and development of fruit. Potassium is responsible for transporting water and nutrients within the plant and supports the production of carbohydrates and sugars.

The manufacturer describes PK 13/14 as a practical tool for gradually increasing phosphorus and potassium levels. The aim is to avoid burdening plants with excess salts at the beginning of flowering, which is particularly important in hydroponics. That is why the supplement is introduced only in the second half of flowering, with the dose increased step by step.

Key features

  • an additional supply of phosphorus and potassium for plants during flowering and fruiting
  • intended for hydroponic growing and coco coir
  • used from the second half of flowering until one week before the end of cultivation
  • dose increased gradually: from 2.5 ml to 15 ml per 10 L of water
  • compatible with Hesi Hydro Bloom and Hesi Coco feeding schedules
  • supports flower formation and fruit set
  • convenient 500 ml bottle

Composition

PK 9-7 fertilizer (manufacturer's declaration); “13/14” in the name is a trade designation, not the nutrient content.

Use

A phosphorus-potassium supplement for the second half of flowering for plants grown hydroponically or in coco coir - at home, on a balcony and in a greenhouse. It is suitable for flowering and fruiting plants: ornamental plants as well as those grown for their own fruit or vegetables. It complements the base fertilizer rather than replacing it: use it together with Hesi Hydro Bloom or Hesi Coco.

Directions for use

  • add the product to nutrient solution water, starting from the second half of the flowering period
  • start with the lowest dose: 2.5 ml per 10 L of water
  • gradually increase the dose in the following weeks, up to a maximum of 15 ml per 10 L of water
  • stop using it one week before the end of cultivation
  • do not exceed the recommended doses - excess phosphorus and potassium unnecessarily increases the salt concentration of the nutrient solution

Safety and storage

Store the product in its original, tightly closed packaging, in a cool, dark place protected from frost, out of the reach of children and domestic animals. The product is not intended for consumption. Avoid contact with the eyes and skin; in case of contact, rinse with plenty of water. Shake the bottle before use. After each use, make sure the packaging is properly closed.
