One of the elements that is indispensable in BIO NOVA's line of liquid mineral fertilizers is magnesium. Magnesium forms the reactive nuclei in the chlorophyll, which converts light energy into chemical energy (ATP and ADP). A deficiency of magnesium manifests itself in chlorosis (slight discolorisation) between the nerves of old leaves and also an early dropping of leaves. An excess results into an ill-growing crop and small leaves. This product has the same characteristics as the other liquid mineral fertilizers offered by BIO NOVA: BN MgO 8 % works very fast. BN MgO 8 % is economic and does not contain excess ingredients. A dosage of 1:1000 increases the total amount of Mg by 2 mmol. BN MgO 8% DOSAGE: In case of deficiencies add 25-100 ml. per 100 liters of nutrient solution. Note that when you are already using one of Bio Nova's main fertilizers a supplement of magnesium is not necessary.
