All of these
Explanation
Solution
Chlorosis is a condition in which leaves produce insufficient chlorophyll. As chlorophyll is responsible for the green colour of leaves, chlorotic leaves are pale, yellow or yellow-white. Chlorosis is typically caused when leaves do not have enough nutrients to synthesise all the chlorophyll they need. It can be brought about a combination of factors including a specific mineral deficiency in the soil, such as iron or magnesium.
