HESI PK 13/14 – PK supplement for hydroponics and coco coir

PK Nutrient for Later Flowering

A phosphorus and potassium supplement for bloom nutrients in hydroponic and coco growing. Does not replace complete base nutrients.

Dosing

The manufacturer recommends 2.5–15 ml per 10 l of water (0.25–1.5 ml/l). Gradually increase the dose from the second half of flowering, following your specific growing schedule and the current product label.

Use

Do not automatically apply the maximum dose from the start of flowering. Excess PK can disrupt nutrient uptake. For soil growing, the manufacturer offers a separate product, Phosphor Plus.

Packaging

Supplied as one pack in the selected size: 500 ml, 1 l, 5 l, 10 l, 20 l.
