Product Details

Product Details

Athena Cal-Mag Fertilizer is formulated specifically for plants in hydroponic systems, providing essential nutrients that support strong growth and development. The blend features vital calcium, magnesium, iron, and nitrogen (NPK 2-0-0), which work together to prevent deficiencies that can slow growth and reduce yields.

Key Benefits

  • Supports strong cell walls and nutrient uptake, encouraging vigorous plant growth.
  • Ideal for tomatoes, peppers, and fruiting plants, preventing issues like blossom end rot and tip burn.
  • Compatible with any fertiliser programme—use alongside base nutrients as needed during the growth cycle.

Hydroponic Compatibility

This fertiliser is essential for use in hydroponic systems, coco coir, and with reverse osmosis water, as these growing conditions tend to deplete calcium and magnesium more quickly than traditional soil setups. It replenishes these nutrients continuously for optimal soilless cultivation.

Usage Instructions

Athena Cal-Mag is a liquid concentrate designed for ease of use with various application methods—including automated dosing systems like Dosatron, hand-watering, and drip irrigation. It is trusted by professional growers and forms part of the Athena Blended nutrient system to ensure consistent, repeatable results.
