Symptoms of Magnesium Deficiency in Plants:
Magnesium deficiency causes chlorosis between the veins and can be seen in a yellowish-orange color. Due to the dynamic nature of Magnesium, deficiency symptoms appear from older leaves. Symptoms of Magnesium deficiency are often confused with Iron and Nitrogen deficiency. (In Nitrogen deficiency, leaves and veins are uniformly yellow, and in Iron deficiency, leaves are yellow and veins are green. However, in Magnesium deficiency, leaves are yellow and veins are green, and the symptoms show first in older leaves.)
Among the indicators of Magnesium deficiency, we can refer to the pale color of the edges of the leaves, chlorosis between the veins and leaf drops.
