CANNA PK 13-14 (PK 13/14) 1 litre

CANNA PK 13-14, labelled PK 13/14, is a phosphorus and potassium supplement for flowering. This bottle contains 1 litre. Use it alongside a suitable feeding programme.

What does PK 13-14 do?

Phosphorus and potassium are nutrients involved in flowering. This supplement adds to the base feed. It is not a complete nutrient, and a higher dose does not guarantee a better result.

When and how to use it

CANNA recommends use three to four weeks before harvest, when flowers are forming across the plant, for no more than one week. The stated dose is 15 ml per 10 litres of water, provided the base feed EC does not exceed 1.8 mS/cm. Check the current label and the schedule for your crop.

Check the finished solution

Shake the bottle, add the measured amount and mix thoroughly. Measure EC and pH after adding the supplement. It can be used with soil, coco and hydroponic systems. Match total feeding to your water, medium and growth stage. Store closed, out of light and protected from frost.
