What Does Magnesium Do?
Magnesium has a wide range of roles in a plant. As magnesium is a building block of chlorophyll, the nutrient’s main role is to aid in the process of photosynthesis and promote healthy, green leaves.
Symptoms Of Magnesium Deficiency:
A plant with a magnesium deficiency will often have yellowing between the veins of the leaves. The leaves will occasionally also have red/brown tints and may fall prematurely.
To rectify a magnesium deficiency, use a fertiliser containing high amounts of magnesium, such as NutriFlo Mag-Sul which contains 6.8% magnesium.
Magnesium Sulphate is also ideal as it contains 16% magnesium oxide.
