Plant Magic Old Timer Organic PK 4-8

Plant Magic Old Timer Organic PK 4-8 is an organic flowering booster designed to increase phosphorus and potassium levels during the critical bloom stage of indoor growing. Created to work alongside Old Timer Grow and Old Timer Bloom, it provides plants with the additional nutrients they need to produce heavier flowers, improved bud density and better overall yield.

During late flowering, plants require increased levels of phosphorus and potassium to support energy transfer, flower formation and nutrient movement within the plant. Old Timer PK 4-8 delivers these nutrients in an organic form that works effectively in soil-based growing systems while maintaining healthy microbial activity in the root zone.

This organic PK booster helps plants focus their energy on producing larger, denser flowers while supporting improved plant health and final crop quality in the grow room.

How It Solves Grow Problems

During the later stages of flowering, plants often require additional phosphorus and potassium to support proper flower development. Without sufficient PK levels, growers may see airy buds, weak flowering sites or reduced yield.

Plant Magic Old Timer Organic PK 4-8 helps correct this by supplying extra bloom nutrients when plants need them most. This supports stronger flower formation and improved bud density while helping plants maintain balanced nutrition throughout the bloom stage.

How to Use

• Designed for soil growing systems.

• Use during the final four weeks of the flowering stage.

• Mix 1–2 ml per litre of water.

• Add to your regular nutrient solution alongside your base bloom nutrient.

• Stir well before feeding plants during regular watering.
