Yellowing (Chlorosis) occur in the newly emerging leaves instead of the older leaves and usually seen in the interveinal region. Fruit would be of poor quality and quantity. Chlorosis occurs in younger leaves because iron is not a mobile element, and as such, the younger leaves cannot draw iron from other areas of the plant.

Therefore, the first sign of magnesium deficiency is the chlorosis of old leaves which progresses to the young leaves as the deficiency progresses. [57] Magnesium also acts as an activator for many critical enzymes, including ribulosebisphosphate carboxylase ( RuBisCO ) and phosphoenolpyruvate carboxylase (PEPC), both essential enzymes in ...
Typical symptoms of potassium deficiency in plants include brown scorching and curling of leaf tips as well as chlorosis (yellowing) between leaf veins. Purple spots may also appear on the leaf undersides. Plant growth, root development, and seed and fruit development are usually reduced in potassium-deficient plants.
Symptoms of nitrogen deficiencies in plants is general chlorosis of the leaves, which is when leaves turn pale green, and leaves cup upwards quite severely in deficient plants. [4] Nitrogen deficiencies also cause leaves to remain small, and drop prematurely, resulting in less photosynthesis occurring in the plant, and fewer, smaller tubers can ...
