Answer
deficiency of Mg and Fe in soil.
Explanation
Solution
Chlorosis is an abnormal condition in plant stems and leaves in which synthesis of the green pigment chlorophyll is inhibited, resulting in a pale yellow colouration. This may be caused by mineral deficiency (N,K, Mg, Mn, Zn, S, Fe and Mo), absence of light, infection (particularly by viruses), or genetic factors.
