Symptoms
Leaves lose their color before developing necrotic patches on the margins.
The secondary veins of younger leaves become prominent or 'ribbed' and leaves may become deformed, distorting into an S-shape.
Young plant leaves may curve downwards starting from the bottom of the tree. This creates trees with a wilting, drooping growth habit.
Reasons
Copper deficiency
Sorry there is no picture available at the moment.
The widespread use of copper based fungiciedes means that Cu deficiencies are rarely seen.
