Athena Blended Line PK – Low-Nitrogen Phosphorus & Potassium Bloom Booster

Athena PK – Low-Nitrogen Bloom Booster for Flowering Plants

Athena PK is a concentrated liquid phosphorus and potassium bloom booster designed to supplement flowering plants from the mid to late flowering stage. Formulated as a balanced complement to bloom fertilisers, Athena PK provides additional phosphorus and potassium while maintaining a low-nitrogen nutrient profile.

The formula is designed to support flowering nutrition without excessively increasing phosphorus or potassium levels, helping maintain balanced nutrient availability throughout the bloom phase. Athena PK is particularly suited to growers using structured feeding programmes who want to supplement their base bloom fertiliser from week 3 of flowering onwards.

Key Features & Benefits

• Balanced PK supplementation – provides additional phosphorus and potassium during the flowering phase.
• Low-nitrogen formulation – designed specifically for mid to late flowering nutrition.
• Complements bloom fertilisers – intended to supplement, rather than replace, a complete flowering nutrient programme.
• Controlled nutrient delivery – formulated to avoid excessively loading the nutrient solution with phosphorus and potassium.
• Suitable for precision feeding programmes – dosage can be adjusted according to crop stage, EC and the appropriate Athena feed schedule.
• Concentrated liquid formula – straightforward to measure and add to nutrient solutions.

How Athena PK Works

During flowering, crop demand for phosphorus and potassium can increase. Athena PK is designed to supplement these elements while maintaining a balanced overall nutrient profile.

Rather than using an excessively strong PK formulation, Athena PK uses a lower-nitrogen approach intended to support elemental balance throughout the flowering stage. It is designed to work alongside an existing bloom fertiliser rather than as a standalone base nutrient.

Technical Specifications

Application & Dilution Rates

Recommended dosage: Add 3–10 mL of Athena PK per US gallon of water, equivalent to approximately 0.8–2.6 mL per litre.

Begin application during the flowering phase from week 3 onwards. Exact application rates should be selected according to crop requirements, EC targets and the appropriate current Athena Feed Schedule.

Best Practice

• Shake well before use.
• Use clean measuring equipment to prevent contamination.
• Do not insert measuring equipment directly into the original bottle.
• Monitor EC regularly and adjust nutrient strength according to crop stage and requirements.
• Mix fertilisers and additives thoroughly before adjusting pH.
• Always check and adjust the final nutrient solution to the appropriate pH range after mixing.
• Store tightly closed in the original container between 7°C and 29°C.
