- deficiencies are rare in Ohio
Magnesium

- progresses rapidly and may turn the entire leaf white

Boron
- irregularly shaped white
spots between veins which could develop into stripes with a waxy, raised appearance
- discoloration found on youngest leaves first, starting at the base of the
leaf and progressing toward the tip
Copper
- youngest leaves become
yellow and stunted, eventually turning pale while the old leaves die back
- dead leaf tissue may appear along the tips and leaf edges in a pattern similar
to potassium deficiency
Zinc
- light green to white streaks
on either side of the mid-rib that may develop into a broad band of bleached
