Zinc deficiency.

It looks as though one of my citrus in pots is suffering a zinc deficiency. In order to send an image to Perry's nursery for diagnosis I brought a leaf inside for scanning and got this rather nice image. It was scanned at 75dpi with a black cloth over it. Then I upped the contrast until the background appeared completely black in my image editor. The cure for the plant, apparently, is a foliar spray of 0.3% (by mass) zinc sulphate solution in spring and autumn.
