Marine Phytoplankton Organic Liquid Plant Food + CALMAG is a fortified version of our iconic Marine Phytoplankton Plant Food, now enriched with essential Calcium (Ca) and Magnesium (Mg) to target two of the most common nutrient deficiencies in plants.While the original MARPHYL Soil Enhancer already provides a full spectrum of micronutrients from up to 80 species of wild marine phytoplankton, Phytoplankton +Cal-Mag adds significant levels of Calcium (0.236%) and Magnesium (0.149%) for targeted benefits and improved performance.
- Key benefits of Phytoplankton + Cal-Mag:.

- Boosts resilience during heat, drought, or transplanting.
- Supports fruit set and prevents common calcium-related disorders.
- Enhances chlorophyll production and energy transfer.
- Improves soil aeration, pH balance, and water infiltration.
- Ideal for crops with high Ca/Mg needs such as tomatoes, peppers, orchids, tropical plants, leafy greens, and fruit trees.
- All of these advantages come with the same ease of use, same 1:20 dilution ratio, and the same clean, ocean-derived formulation you already trust.
