Epsom Salt - Magnesium Sulphate 1kg
Magnesium is very essential for photosynthesis and maintaining healthy, green plant growth. Magnesium deficiency causes yellowing between the veins of older leaves. Veins remain green colour. Under severe deficiency yellowing rapidly increases to a stage where premature drop of leaves and buds can occur.
Dissolve 10 grams of Epsom Salt per litre of water.
