Athena Blended Grow A is the calcium- and nitrogen-forward Part A of Athena’s two-part liquid vegetative base nutrient. With an N-P-K of 4-0-1, it supplies nitrogen, calcium, magnesium, and a full chelated micronutrient package. It is designed to be used in equal volumes with Grow B throughout the vegetative phase, with the two concentrates kept separate until they are diluted into the irrigation water. The sediment-free liquid is suitable for fine-drip emitters, proportional dosing systems, and a range of hydroponic and soilless media.
• Brand: Athena
• Product Line: Blended Line
• Product Type: 2-part liquid vegetative base nutrient — Part A
• N-P-K: 4-0-1
• Total Nitrogen: 4.0% — 3.8% nitrate nitrogen, 0.2% ammoniacal nitrogen
• Calcium (Ca): 4.2%
• Magnesium (Mg): 0.19%
• Chelated Iron (Fe): 0.06% — EDTA + EDDHA
• Boron (B): 0.01%
• Application Rate: 2–15 mL per gallon
• Mixing Ratio: Equal parts Grow A and Grow B
• Growth Stage: Vegetative — propagation through the transition to flower
• Required Companion: Athena Blended Grow B
• Media Compatibility: Coco, rockwool, DWC/recirculating systems, peat, and soil
• Formula: Sediment-free liquid concentrate
• Fine-Dripper Compatibility: Yes — suitable for Topspin, Floraflex, and similar fine-drip emitters
• Injection Compatibility: Compatible with Dosatron, Netafim, and proportional dosing systems
• Micronutrient Package: Chelated iron, manganese, zinc, copper, boron, and molybdate
• Iron Chelation: EDTA and EDDHA
• Primary Role: Supplies nitrogen, calcium, and the micronutrient fraction of the Grow A/B program
• Grow B Role: Supplies phosphorus, additional potassium, and sulfate-form magnesium
• Mixing Procedure: Add Grow A and Grow B separately to dilution water; never combine the concentrates directly
• Program Transition: Grow A/B are replaced by Bloom A/B at the transition to flowering rather than being run concurrently
• Supplement Compatibility: Can be used with Athena CaMg, Balance, PK booster, and Cleanse according to the Blended Line program
• Sizes: 1,5,55-gallons and 275-gallon IBC totes available
Key Advantage: Grow A provides the nitrogen, calcium, and chelated micronutrient foundation of Athena's vegetative program in a sediment-free liquid that is suitable for precision dosing and fine irrigation emitters. Its two-part design keeps incompatible nutrient salts separated in concentrate form, while equal-volume mixing with Grow B creates the complete vegetative nutrient solution.
