MED-TEK COIR VEGA BASE A B Many Australian growers ‘veg’ for a long time. Some nutrient manufacturers only produce and sell a single base coir nutrient formula that is to be used in grow and bloom. As a result, growers are then advised to use an N top up additive to boost N in the vegetative growth stage. However, this is far from perfect because other than higher N requirements, other things are also going on which influence what would be considered optimal plant nutrition during veg versus flower. Coir Vega is an aggressive, high N to K ratio, vegetative nutrient that promotes vigorous new leaf and shoot growth without compromising the plant structure and health. Coir Vega is loaded in calcium and magnesium. Our research has found that, particularly early on in the crop cycle, the coir substrate exchange sites lock up a high degree of the calcium and magnesium that is provided via the nutrient solution. This situation may go on for several weeks. Therefore, Coir Vega is formulated in such a way as to compensate for calcium and
