PK 4-8 provides an extra boost of organic potassium and phosphorus to your plants and is created to work in harmony with Oldtimer Grow and Bloom. This encourages higher yields with denser and more flowering plants.
Use of Oldtimer PK is ideal for plants that were grown in soil. The Plant Magic feeding schedule advises using it at a rate of 1-2ml per litre during the final four weeks of the flowering stage.
Plant Magic PK 4-8 is available in 1L, 5L & 10L bottles.
