Mineral deficiency. Mineral deficiency is the situation where a plant cannot get enough of a particular mineral from the soil for healthy growth. The tomato plant on the left is healthy, the one
The major roles and deficiency symptoms of mineral elements in the plants are as follows: Nitrogen: Plants absorb nitrogen mainly in the form of nitrate ions. It is a structural component of amino acid, nitrogenous bases, nucleic acid etc.
Second most common deficiency in CA. Particularly common with "acid loving" plants who are poor mineral absorbers and function best in acid soils. Iron availability and form in soils depends on parent material chemistry and pH. Fe is unavailable at pH < 5 as iron phosphates form. Fe is unavailable in alkaline lime containing soils.

Present in DNA, RNA, phospholipids membranes, ADP, ATP, etc. Plants grow poorly and leaves are dark green with purple tints.
pH problems, mineral imbalances, poor drainage, mostly cause the Fe deficiency, not a lack of Fe in the soil. Fe is unavailable in dry climate soils, especially when the pH>8 Deficiency
