VitaLink CalMag additive contains calcium and magnesium, two vital elements for strong plant growth. This is an ideal product for growers of all levels and can be added throughout the plant growth life cycle because it is an immobile product that can’t travel to areas of new growth. Use VitaLink CalMag product alongside your chosen nutrients.
Use 1ml/1L for the first 3 weeks of vegetative growth in coco coir media, or when calcium is short in supply.
