Advanced PK is a high-quality fertilizer with a balanced phosphorus-potassium ratio and is ideal for the formation of buds.

Use:
Advanced PK is recommended as a supplement in the recipe of the Dutch Formula, from the first flower development to a week before the harvest.

Dosage:
First add 1 ml Advanced PK to a liter of standard nutrition. Then you fill up the fertilizer until the desired EC value is reached. Use this enriched nutrient combination for every irrigation during the flowering phase.

Shake well before use.
