Humboldts Secret's CalMag & Iron supplement is designed to address common plant deficiencies. It is a source of calcium, magnesium, and chelated iron, which are essential micronutrients for many flowering plants. The formula effectively corrects and remedies these micronutrient deficiencies, supporting nutrient uptake and absorption, and ensuring strong and healthy plants and yields.

The supplement is suitable for hydroponics, soil, and container gardens, and is highly recommended for plants growing in coco substrate or reverse osmosis water, as the absorption process becomes magnified in these growing mediums. With Humboldts Secret, growers can achieve optimal results and succeed in their growing endeavors.
