PK Top Up™ – High-Potassium & Phosphorus Booster for Bigger Flowers & Better Harvests
PK Top Upâ„¢ is a highly concentrated flowering supplement formulated to provide additional phosphorus (P), potassium (K) and essential trace elements during the critical flowering and fruiting stages of plant development. Using premium quality soluble ingredients, PK Top Upâ„¢ helps support larger flowers, stronger fruit development and improved crop quality, while delivering exceptional value through its highly concentrated formula that requires only small application rates.
As plants transition from vegetative growth into flowering, their nutritional demands change significantly. During this period, the requirement for phosphorus and potassium increases as energy is redirected towards flower formation, fruit development and seed production. If these nutrients become depleted, flowering can slow, flower retention may decrease and fruit quality can suffer. PK Top Upâ„¢ helps replenish these essential nutrients, ensuring plants continue to perform at their full potential throughout the reproductive cycle.
Phosphorus is essential for energy transfer, root activity and flower formation, while potassium plays a vital role in water regulation, sugar transport and overall plant metabolism. Together, these nutrients contribute to improved flower size, richer colour, enhanced flavour and stronger fruit development. The added trace elements further support healthy plant function by maintaining balanced nutrition during periods of rapid growth.
For best results, continue using Nitro-Kâ„¢ throughout the vegetative stage until flowers and buds become visible. Once flowering begins, transition to PK Top Upâ„¢ to replace the higher nitrogen requirements of vegetative growth with the increased phosphorus and potassium needed for flowering and fruit production. Using the two products in succession provides a smooth nutritional transition that helps maximise yield potential while improving crop quality, flavour and overall finish.
Suitable for hydroponics, coco, soil and both run-to-waste and recirculating systems, PK Top Upâ„¢ is easy to incorporate into any feeding program. Regular flushing of recirculating systems is recommended to minimise nutrient and organic residue build-up.
Top up your phosphorus and potassium when your plants need it most and enjoy healthier flowers, stronger fruit development and consistently higher-quality harvests with PK Top Upâ„¢.
