HY-GEN PK Top Up | 500ml, 1L, 5L, 20L | Phosphorus and Potassium Flowering Booster

🌸 HY-GEN PK Top Up | Available in 500ml, 1L, 5L and 20L

When your plants hit the flowering and fruiting stage, they need more phosphorus and potassium than your base nutrients alone can provide. HY-GEN® PK TOP UP™ is a highly concentrated, premium quality PK booster designed to step in at exactly the right time and give your plants the extra push they need for bigger, better, more colourful harvests. 🌱

A small dose goes a long way, making it one of the most cost-effective additives you can add to your feeding program.

✅ Why Growers Use PK Top Up

• 🌺 Boosts Flower and Fruit Quality: Phosphorus and potassium work together to improve colour, density and the flavour of your final harvest
• 💪 Strengthens Cells in Roots and Fruit: Supports strong cell walls for firmer, healthier fruit and a more robust root system
• ⚡ Highly Concentrated Formula: You only need a small amount per litre, so each bottle goes further than you'd expect
• 🧪 Corrects Deficiencies Fast: When phosphorus and potassium levels drop during flowering, PK Top Up brings them back to optimal quickly
• 🌿 Trace Element Booster: Supplies additional trace elements alongside P and K to support overall plant health during the most demanding stage of growth
• 🛡️ Improves Buffering Capacity: Helps your nutrient solution stay stable and balanced throughout the flowering window
• 📈 Improves Yields: Regular use during flowering and fruit set leads to visibly improved quality and quantity at harvest

🗓️ How and When to Use It

Start using PK TOP UP™ once you see the first visible signs of flowers and buds forming. Before that point, continue using HY-GEN® NITRO-K™ to maintain potassium levels while nitrogen is still needed.

Using NITRO-K™ and PK TOP UP™ in succession gives you a seamless transition from vegetative growth into full flowering, ensuring your plants never run short of the nutrients they need most.
