Advanced Nutrients HammerHead PK 4/12 250 ml – 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 base fertilizer during the middle of flowering, when plants are flowering intensively and setting fruit.

The formula contains no added nitrogen. The base fertilizer already provides an adequate amount of this element, while excess nitrogen during the flowering phase can inhibit growth, cause leaf yellowing and weaken flowering. Potassium is supplied as potassium citrate 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 litre, the 250 ml bottle can prepare approximately 125 litres 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, fruit set and fruit development
  • formulated 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 plant 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 litre of nutrient solution during flowering weeks 3–7. 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. The 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.
