Athena Pro Core

Athena Pro Core – Professional Powdered Base Nutrient

Athena Pro Core is a fully water-soluble powdered base nutrient designed to provide essential nitrogen, calcium and micronutrients throughout the plant growing cycle. As a key component of the Athena Pro Line, Pro Core works alongside Athena Pro Grow or Pro Bloom to create a balanced feeding programme for vegetative growth, flowering and fruit development.

With an NPK ratio of 14-0-0, Pro Core supplies nitrogen to support chlorophyll production and healthy vegetative development, alongside calcium for strong plant structure and a carefully selected range of micronutrients required for normal plant metabolism.

Designed for professional horticulture, Pro Core features a highly soluble, large-grind powder that dissolves cleanly in water when mixed correctly. Its low-sediment formulation makes it particularly suitable for concentrated stock tanks, automated fertigation systems and commercial hydroponic operations.

Whether you're managing a large irrigation installation or preparing nutrient solutions manually, Athena Pro Core provides a reliable foundation for consistent mineral nutrition throughout the growing cycle.

Key Features & Benefits

• Essential base nutrient: Supplies nitrogen, calcium and micronutrients throughout vegetative growth and flowering.
• Designed for Athena Pro Grow & Bloom: Works alongside either product to create a complete Pro Line feeding programme.
• Supports healthy plant growth: Nitrogen contributes to chlorophyll production, amino acid formation and normal plant development.
• Provides calcium: Supports cell wall development, plant structure and healthy growing tissues.
• Contains chelated micronutrients: Supplies essential trace elements in forms designed for nutrient solution availability.
• Fully water-soluble: Dissolves in water without significant sediment when prepared correctly.
• Suitable for automated fertigation: Designed for compatible professional dosing and irrigation systems.
• Ideal for concentrated stock tanks: Can be prepared as a stock solution for controlled nutrient injection.
• Suitable throughout the growing cycle: Used with Pro Grow during vegetative development and Pro Bloom during flowering.
• Dry powder format: Convenient for storage, transport and preparing nutrient solutions as required.

Why Use Athena Pro Core?

Healthy plant growth depends on a consistent supply of essential mineral nutrients. While nitrogen, phosphorus and potassium are often the main focus of fertiliser programmes, calcium and micronutrients are equally important for normal plant development.

Athena Pro Core provides these essential nutrients as part of the complete Athena Pro Line feeding system.

Its formulation is designed to complement the phosphorus, potassium and other minerals supplied by Athena Pro Grow or Pro Bloom, allowing growers to maintain balanced nutrition throughout different growth stages.

Using a separate Core component also allows calcium-containing fertilisers to be stored independently from concentrated phosphate and sulphate fertilisers, helping reduce the risk of unwanted precipitation in stock solutions.

What Nutrients Does Athena Pro Core Provide?

Athena Pro Core contains nitrogen, calcium and a range of essential micronutrients that support plant growth and development.

• Nitrogen (N): Essential for chlorophyll production, amino acid synthesis, proteins and healthy vegetative growth.
• Calcium (Ca): Supports cell wall structure, membrane function and the development of healthy growing tissues.
• Iron (Fe): Plays an important role in chlorophyll formation and essential metabolic processes.
• Manganese (Mn): Contributes to photosynthesis and enzyme activity.
• Zinc (Zn): Supports enzyme function and normal plant growth regulation.
• Copper (Cu): Involved in enzyme systems and plant metabolic processes.
• Boron (B): Important for cell wall development and normal growing-point function.
• Molybdenum (Mo): Supports nitrogen metabolism and the conversion of nitrate into forms plants can use.

These nutrients work together to support healthy plant development. Deficiencies or imbalances can affect growth even when the main NPK nutrients are present in sufficient quantities.

How Athena Pro Core Works with Pro Grow & Pro Bloom

Athena Pro Core is not intended to be used as a standalone fertiliser. It must be combined with the appropriate Athena Pro Line base nutrient.

During vegetative growth: Use Athena Pro Core alongside Athena Pro Grow to supply the nutrients required for healthy roots, stems and foliage.

During flowering and fruit development: Use Athena Pro Core alongside Athena Pro Bloom to provide balanced nutrition for reproductive growth.

The stated reservoir mixing ratio is 0.6g of Pro Core for every 1g of Pro Grow or Pro Bloom, subject to the appropriate Athena feeding schedule.

This allows growers to use the same Core component throughout the growing cycle while changing the accompanying fertiliser to match the plant's development stage.

How to Use Athena Pro Core

Athena Pro Core can be mixed directly into a nutrient reservoir or prepared as a concentrated stock solution for use with compatible dosing equipment.

Always measure powdered nutrients by weight using accurate scales rather than estimating quantities by volume.

Mixing Athena Pro Core in a Reservoir

When preparing a nutrient solution directly in a reservoir, use 0.6g of Pro Core for every 1g of Pro Grow or Pro Bloom, following the appropriate Athena feeding schedule.

1. Fill your reservoir with the required amount of clean water.
2. Measure the required amount of Athena Pro Grow or Pro Bloom according to your feeding schedule.
3. Add the measured Grow or Bloom powder to the water and mix thoroughly until dissolved.
4. Measure Athena Pro Core at 60% of the weight of Grow or Bloom.
5. Add Pro Core to the diluted nutrient solution and mix thoroughly.
6. Allow the nutrients to dissolve completely.
7. Check the electrical conductivity (EC) of the finished solution.
8. Measure and adjust the final pH as required.

Important: Never combine Pro Core with Pro Grow or Pro Bloom in their dry forms or as undiluted stock concentrates. Always dissolve and dilute the products separately to avoid unwanted mineral reactions.

Preparing Athena Pro Core Stock Concentrate

Athena Pro Core can be prepared as a concentrated stock solution for use in compatible automated fertigation systems.

Maximum stock mixing rate: 1.1kg per 4 litres of water, according to the supplied product instructions.

1. Prepare a clean stock tank with the required amount of water.
2. Measure the Pro Core powder accurately by weight.
3. Slowly add the powder to the water while mixing.
4. Continue mixing until the powder has fully dissolved.
5. Keep Pro Core concentrate separate from Pro Grow and Pro Bloom concentrates.
6. Connect the stock tank to a compatible dosing system.
7. Set the injection rate according to the required nutrient solution strength.
8. Measure the final EC and pH after dosing.

Do not exceed the manufacturer's recommended stock concentration. Water temperature and water quality can affect solubility.
