interveinal chlorosis of leaves is caused by the deficiency of

We already know that Magnesium is a central part in chlorophyll, but there are other essential elements like Iron, Manganese, and Molybdenum that are necessary in many enzyme activities, and a deficiency in one of these nutrients can lead to interveinal chlorosis. Even though there typically is plenty of iron in these soils, the high soil pH causes chemical reactions that make the iron solid and unavailable to plant roots. On result, chlorotic plants often produce smaller fruits, poor in quality sometimes with unusual (bitter) flavour of fruit too. Iron is not a constituent of chlorophyll but its deficiency causes chlorosis. Leaves of affected plants are yellow, light green, or white with distinct green veins resulting in interveinal chlorosis.
