Advanced Nutrients HammerHead PK 4/12 1 L – nitrogen-free PK flowering booster

HammerHead PK 4/12 by Advanced Nutrients is a liquid flowering booster that supplies plants with phosphorus and potassium in a 1:3 ratio. It is used as an addition to a base fertilizer during the middle of flowering, when plants are flowering intensely and setting fruit.

The formula contains no added nitrogen. The base fertilizer already provides an appropriate amount of this element, while excess nitrogen during the flowering phase can inhibit growth, cause yellowing leaves and weaken flowering. Potassium comes from potassium citrate, used instead of potassium sulfate. Citrate acts as a chelating agent and, according to the manufacturer, helps plants absorb phosphorus and other nutrients.

At a dosage of 2 ml per liter, the 1 L bottle can prepare approximately 500 liters of nutrient solution.

Key features

  • phosphorus and potassium in a 1:3 ratio (PK 4/12)
  • no added nitrogen – lower risk of nitrogen overfertilization during the flowering phase
  • potassium citrate as a source of potassium and a chelating agent
  • supports flowering as well as fruit set and development
  • developed for use with Sensi Terra base fertilizers, and also compatible with pH Perfect fertilizers and fertilizers from other brands
  • according to the manufacturer, contains no paclobutrazol, daminozide or other prohibited growth regulators

Composition and NPK analysis

NPK 0-4-12 (label value): phosphorus (P2O5) 4%, potassium (K2O) 12%, with no added nitrogen. Potassium comes from potassium citrate.

Uses

HammerHead supports plants during full flowering, when they are setting and developing flowers and fruit – from ornamental and balcony plants to fruiting vegetables grown at home, in a greenhouse or in the garden. The manufacturer designed it primarily as a supplement to Sensi Terra base fertilizers, but it can also be combined with pH Perfect base fertilizers, fertilizers without this technology, and fertilizers and additives from other manufacturers.

Directions for use

Add 2 ml of the product per 1 liter of nutrient solution during weeks 3–7 of flowering. Pour the concentrate into water containing dissolved base fertilizer and mix thoroughly.

Safety and storage

Store the concentrate in its original, tightly closed container, in a cool, shaded place, away from frost and direct sunlight. Keep the product out of reach of children and pets. This product is not intended for consumption. Avoid contact with the eyes and skin; in case of splashing, rinse with plenty of water. Wash your hands after handling the fertilizer.
