Calcium & magnesium are critical to healthy plant growth cycle. Calcium plays an important role in the development of strong plant tissue & roots, while magnesium is essential in the process of chlorophyll production and photosynthesis. Important for blooming and flowering as well, magnesium encourages strong, healthy veins & stimulus on newly emerging leaves. Blended at the perfect 2:1 ratio, which has great impact on both overall health & yield. Since calcium is not mobile in the plants, it is crucial to maintain proper calcium levels throughout the plants life cycle, which can be done with root or foliar applications. 100% sugar-acid chelate (glucoheptonate) works fast to correct problematic deficiencies of both Calcium & Magnesium. Product can be applied both as a foliar spray or soil drench to avoid deficiencies. Unlike chemical synthetic chelates, it has a near neutral pH of 6, is biodegradable, and is a food source for soil microbes. Makes up to 128 gallons depending on application.
