Symptoms
Interveinal areas become pale yellow, while veins remain green. Symptoms show first at the bottom half of the leaf. With ongoing deficiency the chlorotic tissue may turn brown. Only old or mature leaves are affected, but premature leaf shedding is not common.
Symptoms can appear similar to those for potassium deficiency.
Reasons
Magnesium deficiency.
High levels of potassium and/or calcium can restrict and compete with uptake of magnesium, so it is important that these nutrients are well balanced.
Especially in cocoa, good magnesium supply is important to boost the plant’s tolerance to high levels of sunlight. This means it is particularly important to maintain adequate Mg levels in mono-cultivated cocoa plantations.
