Hesi PK 13/14, 5L

Premium Phosphorus-Potassium Booster for Flowering Plants

Hesi PK 13/14 is a specialized organomineral flowering nutrient designed to maximize your plants' reproductive potential during the critical flowering phase. This professional-grade phosphorus and potassium supplement delivers rapid, direct nutrient uptake that transforms ordinary blooms into dense, compact, and substantial flowers. Perfect for hydroponic and coco cultivation systems, this concentrated formula provides the essential building blocks your plants need when it matters most.

Key Features and Benefits

This premium flowering enhancer combines optimal ratios of phosphorus and potassium in a highly bioavailable form that plants can immediately utilize. The organomineral composition ensures both quick results and sustained nutrient release throughout the flowering cycle.

• Accelerated flower formation with significantly larger bloom development
• Enhanced flower density and compactness for higher yields
• Rapid and direct phosphorus-potassium absorption by plant roots
• Compatible with all growing media except soil-based mixtures
• Perfectly balanced NPK ratio specifically formulated for flowering phase
• Organomineral formula combining fast-acting synthetic nutrients with organic components
• Professional-grade concentration requiring minimal storage space

Application and Usage Guidelines

Hesi PK 13/14 should be introduced during the flowering phase following a precise weekly escalation schedule. This graduated approach allows plants to adapt to increasing nutrient levels while maximizing flowering potential. The supplement works exceptionally well when combined with Hesi Hydro or Hesi Coco base nutrient lines, creating a complete flowering nutrition program.

Begin application during the fourth week of flowering and gradually increase dosage through week seven, then finish with pure water flushing. This methodology ensures optimal nutrient uptake while preventing nutrient lockout or burning. Always shake well before use and store in a cool, dry location away from direct sunlight.

Recommended Dosage Schedule

Follow this proven feeding schedule for maximum flowering results:

• Week 4: 2.5ml per 10L of water
• Week 5: 5ml per 10L of water
• Week 6: 10ml per 10L of water
• Week 7: 15ml per 10L of water
• Week 8: Pure water flush only

Ideal Combinations and Compatibility

For optimal results, combine Hesi PK 13/14 with complementary growing supplies from the Hesi product line. The most effective combinations include Hesi SuperVit for enhanced vitamin supplementation, PowerZyme for improved nutrient cycling, and HesiBoost for additional flowering stimulation. These products work synergistically to create an optimal flowering environment.

This flowering booster is specifically formulated for hydroponic systems and coco coir growing media. It is not recommended for soil-based growing mixtures, as the concentrated formula may cause nutrient imbalances in organic soil environments.
