Know before you buy
Many plants, especially those grown in coco coir or hydroponic systems, can develop deficiencies that lead to issues like blossom end rot or tip burn. CALiMAGic supplements these essential secondary nutrients to ensure your plants have the building blocks needed for vigorous, healthy growth.
Yes, it is designed to be used as a supplement alongside your primary nutrient program. Because it has a 1-0-0 NPK ratio, it provides minimal nitrogen and focuses primarily on correcting or preventing calcium and magnesium deficiencies.
While it is specifically formulated for the high demands of hydroponics and soilless media like coco coir, it can also be used for soil-grown vegetables and houseplants. It is particularly helpful if your local water source is low in calcium or magnesium.
As a synthetic, mineral-based concentrate, CALiMAGic is highly bioavailable, meaning your plants can absorb the nutrients quickly. This provides a consistent and reliable way to address deficiencies compared to organic amendments that may take longer to break down.
Like most concentrated liquid fertilizers, adding CALiMAGic can influence the pH of your water or nutrient reservoir. It is recommended to add it to your water first, mix thoroughly, and then check and adjust your pH levels before adding other nutrients.
