Manganese and zinc deficiency-Strawberry

Symptoms
Manganese deficiency causes yellow-green intercostal chlorosis on young and medium old leaves. Green veins give the leaf surface a netlike appearance. Zinc undersupply causes chlorosis on both younger and older leaves. Veins and the serrated leaf margins remain green.

Reasons
Manganese and zinc deficiency Deficiencies of both micronutrients occur often in some regions, occasionally even at the same time. They are hard to distinguish without further testing. Iron deficiency can be a reason for chlorosis on the youngest leaves, while magnesium undersupply causes chloroses on older leaves.

Symptoms
Manganese deficiency causes yellow-green intercostal chlorosis on leaves. Especially the medium aged, large leaves show distinct dark green veins and leaf margins. On the youngest leaves the chlorosis looks more uniform as the small veins are only slightly darker than the adjacent tissue.

Reasons
Manganese deficiency on leaves Symptoms can be confused with magnesium deficiency, but in this case interveinal chlorosis starts on old leaves.
