Athena Blended Line Bloom A & B is a professional two-part liquid mineral fertiliser formulated for flowering and fruiting plants. Designed for precision horticulture, Athena Bloom combines essential macronutrients with chelated micronutrients to provide balanced mineral nutrition throughout the flowering and fruiting stages.

Bloom A and Bloom B are designed to be used together in equal quantities, maintaining the intended mineral ratios while allowing growers to adjust nutrient strength according to crop requirements and target EC.

The clean, highly soluble liquid formulation is suitable for hydroponics, coco, soilless growing media, hand watering and automated fertigation systems, including systems using fine drippers.

Key Features of Athena Bloom

  • Professional two-part liquid flowering nutrient
  • Bloom A & Bloom B are used in equal quantities
  • Contains macronutrients and chelated micronutrients
  • Formulated for flowering and fruiting plants
  • Suitable for hydroponics, coco and soilless growing media
  • Compatible with hand watering and automated fertigation
  • Suitable for modern dosing and irrigation systems
  • Clean, highly soluble mineral formulation
  • Compatible with fine dripper irrigation systems
  • Allows nutrient strength to be managed through EC
  • Part of the complete Athena Blended Line nutrient programme

Clean & Precise Plant Nutrition

Athena developed the Blended Line for growers looking for a straightforward liquid mineral feeding programme without an unnecessarily complicated selection of additives.

During the flowering stage, Athena Bloom A and Bloom B replace Grow A and Grow B as the base fertiliser, providing a mineral profile designed for the changing nutritional requirements of flowering and fruiting plants.

The formula is designed to remain clean in solution and is compatible with modern irrigation and dosing equipment. This makes Athena Bloom particularly suitable for precision irrigation, automated fertigation and high-frequency watering systems where reliable nutrient delivery is important.

Suitable for Hydroponics, Coco & Automated Irrigation

Athena Bloom can be incorporated into a wide range of professional and hobby horticultural systems, including:

  • Hydroponic growing systems
  • Coco coir
  • Rockwool
  • Soilless growing media
  • Drain-to-waste systems
  • Hand watering
  • Drip irrigation
  • Precision irrigation
  • Automated dosing and fertigation systems

Its liquid formulation also makes measuring and adjusting nutrient concentration straightforward when managing a feeding programme around a target EC (electrical conductivity).

How to Use Athena Bloom A & B

Always use Athena Bloom A and Bloom B in equal quantities.

Add each component separately to water and mix thoroughly. Do not combine Bloom A and Bloom B together in their concentrated form.

Athena's Blended Line feed programme varies the application rate throughout the flowering cycle.

As an example, Athena's metric schedule currently recommends:

Flower Weeks 1–4:
32 ml Bloom A + 32 ml Bloom B per 10 litres of water
Equivalent to 3.2 ml/L of Bloom A + 3.2 ml/L of Bloom B

Rates are reduced during later stages of the programme, so always refer to the current Athena Blended Line Metric Feed Schedule for the complete week-by-week feeding programme.

Mixing Best Practice

  1. Start with clean water in your reservoir.
  2. Shake Bloom A and Bloom B well before use.
  3. Measure and add the required amount of Bloom A to the water.
  4. Mix thoroughly.
  5. Measure and add an equal amount of Bloom B.
  6. Mix thoroughly before adding other compatible products.
  7. Check the final EC and adjust according to crop requirements.
  8. Check and adjust pH after all fertilisers and additives have been mixed.

Never mix concentrated Bloom A and Bloom B directly together.

Variable EC Feeding

The Athena Blended Line has been designed to allow growers to fine-tune nutrient concentration throughout the plant growth cycle.

Rather than maintaining exactly the same nutrient strength from beginning to end, growers can adjust EC according to plant development, growing environment and crop requirements.

Athena separates products such as CaMg and PK from the base fertiliser, providing additional flexibility when building a crop-specific feeding programme.

Part of the Athena Blended Line

Bloom A & B form the flowering-stage base fertiliser within the Athena Blended Line.

The complete programme can incorporate complementary Athena products such as CaMg, PK, Cleanse and Balance depending on the growing method, water source and feeding strategy being used.

This streamlined approach makes Athena Blended Line particularly well suited to growers who want the convenience of concentrated liquid nutrients combined with precise control over their feeding programme.
