When this happens, the leaves do not have normal Green staining; a pale green, yellow, yellow coloration is whitish. Affected plants have decreased their ability to form carbohydrates and can die if the cause of its chlorophyll insufficiency is not treated. Specific deficiencies of nutrients ( frequently aggravated by a high level of pH ) they produce chlorosis, which could be corrected supplementing with iron, magnesium and nitrogen in various combinations. You can also be an excess of calcium. Some pesticides, particularly herbicides may cause chlorosis, both weeds and occasionally treated cultures.
