OrganaGrow Cal-Magic

OrganaGrow Cal-Magic 1L is a high-quality calcium and magnesium plant supplement specially formulated to support stronger plant structure, improved nutrient uptake, and vigorous overall growth. Designed for use in hydroponic systems, coco coir, soil, and other growing media, this essential additive helps prevent and correct common calcium and magnesium deficiencies in fast-growing plants.

Rich in bioavailable calcium and magnesium, OrganaGrow Cal-Magic plays a vital role in cell wall development, chlorophyll production, photosynthesis, and nutrient transport. It is especially beneficial for heavy-feeding plants, flowering crops, and plants grown under LED grow lights, where calcium and magnesium deficiencies are more common.

This versatile plant nutrient additive helps strengthen stems, stalks, and leaves, promoting healthier growth and improved plant resilience. It may also assist in creating a less favourable surface environment for powdery mildew and certain pests when used as part of a balanced plant care routine.
