Highly concentrated basic fertilizer with a complete set of macro elements necessary for intensive plant growth. AF Macro is a carefully selected composition with nitrogen, phosphorus and potassium (NPK) enriched with magnesium. Regular use of AF Macro ensures fast and healthy growth of plants and guarantees their intense and natural coloration. The perfect ratio of macronutrients provides all the necessary substances that plants use in their natural environment. Macro elements participate in cell structures, the development of proteins and enzymes, and they are also part of nucleic acids. AF Macro is not only the basic building block, but its components also transport and accumulate energy. Deficiency of macro-elements causes growth inhibition, weakening of shoots and discoloration of leaves. AF Macro is perfect for heavily planted aquariums with a small amount of fish.
