  • Athena CaMg
    Athena CaMg

    Athena CaMg is designed to supplement either of our 2-part liquid formulas. Some cultivars and growing conditions may require higher doses of Calcium, Magnesium, Iron and Nitrogen during heavy growth and development phases. This product effectively corrects these common deficiencies without throwing off overall elemental balance. In systems using reverse osmosis (RO) water and plants grown in inert media, such as coco and rockwool, Athena CaMg is particularly useful. Although our 2-part formulas already provide sufficient levels of Calcium and Magnesium, some growers require find supplementation helpful in demanding conditions.


    Application Rates

    Add 2.5 mL per gallon of water during all stages as needed.


    See Feed Schedules for specific application recommendations.

    Best Practices

    Shake well before use.

    • Use clean measuring instruments--do not put anything into the bottle.
    • Some applications may require different dosages.
    • Recommended for hydroponic use, especially with inert media and when using reverse osmosis (RO) water.
    • Monitor EC regularly and adjust accordingly based on crop and growth stage.
    • Adjust to pH to proper levels after mixing all fertilizers and additives.
    • Store closed in original packaging at a temperature between 45° F and 85° F.
