Plant Magic Platinum PK 9/18 is a highly concentrated flowering booster designed to deliver powerful levels of phosphorus and potassium during the bloom stage. In hydroponics and indoor growing, plants require increased PK levels during flowering to support heavy bud formation, improved bud density and higher yields.
This potent additive helps plants direct more energy into flower production at the most critical stage of the cycle. By supplying additional phosphorus for energy transfer and potassium for nutrient movement and plant strength, Platinum PK 9/18 encourages stronger flowering sites, improved terpene production and better overall crop quality. It works effectively across soil, coco and hydroponic systems, making it suitable for a wide range of grow room setups.

How It Solves Grow Problems
Many growers experience airy buds or reduced yields when plants do not receive enough phosphorus and potassium during the bloom stage. As flowering progresses, plants demand higher PK levels to support energy production and flower formation.
Plant Magic Platinum PK 9/18 provides a strong PK boost during mid to late flowering, helping plants develop denser flowers and stronger bud sites. By supporting efficient nutrient movement and plant metabolism, it helps growers maximise flowering performance and achieve heavier harvests in the grow tent or grow room.
How to Use
-
Use during weeks 4–8 of the flowering stage.
-
Suitable for soil, coco and hydroponic systems.
-
Mix 0.25–0.5 ml per litre of water.
-
Add to your regular nutrient solution alongside your base bloom nutrient.
-
Stir thoroughly before feeding plants.
Used correctly, Platinum PK 9/18 helps plants produce fuller, denser flowers while improving the overall quality and yield of the final harvest.
