Advanced PK is an essential supplement for the flowering phase:
- Phosphorus provides the energy required for the development of a strong and healthy rooting system.
- Potassium improves water transport through the plant.
Advanced PK is recommended as a supplement to regular fertilisation from the start of the flowering period until a week before harvesting.
Directions for use:
- Add 1 ml Advanced PK/1 L water. Then mix with your basic nutrient solution for each stage. Measure EC values.
- Use Advanced PK in each watering during the whole flowering period.
