Zinc deficiency-Raspberries

Symptoms
Older leaves are vaulted downward or contorted and show interveinal chlorosis. Deformations have been reported from younger leaves, too. With ongoing deficiency mature leaves display a dark green, later brown marginal discoloration that finally spreads allover the leaf blade. Plant size is reduced.

Reasons
Zinc deficiency Suggested range is 16-80 ppm in leaf tissue. Zinc content in soils is often good while its availibility is not sufficient. Excessively high soil pH should be avoided.
