VitaLink Coir MAX is a highly-concentrated A and B formulation, tailor-made to get the best possible results when growing in coco coir. This 2-part nutrient contains a balanced mix of macro and micronutrients and is ideal for use throughout both growth and flowering stages. Fulvic acid and chelated micronutrients improve plants’ uptake of nutrient solution, resulting in better photosynthesis and thus more vigorous growth and flowering. Iron is chelated with EDDHA, making it available over a wide pH range, so your plants will never starve for this element – even in the periods of high-demand. Iron is necessary for production of chlorophyll, which is essential for photosynthesis.
