Element deficiencies where younger leaves are affected first

Calcium Deficient (16K)

Sulphur Deficient (19K)

Boron Deficient (15K)
Terminal buds die, distortion and necrosis of young leaves, die back at tips and margins. Root tips gelantinous and swollen. Decreased leaf size, pale green-yellow leaves, shortened internodes. Leaf veins become chlorotic. Young leaves light green-yellow at base, die back of terminal bud, leaves misshapen, thick, brittle and small. Cracks and splits occur in petioles and stems. Root tips enlarged.

Copper Deficient (20K)

Iron Deficient (23K)

Manganese Deficient (26K)
Young leaves permanently wilted, without chlorsis. Leaves rolled or curled. Emerging leaves often trapped in subtended leaves. Pollen cells often sterile. Uniform chlorosis of younger leaves, veins remain darker green. Chlorosis often interveinal and produces a bold pattern of dark green major veins. Unlike iron, necrotic spotting or lesions appear on affected leaves. These may be brown to black.

Zinc Deficient (25K)
Leaf malformation, irregular mottling with yellow-ivory interveinal areas and extreme rosetting of terminal and lateral shoots in woody species. In some cases necrotic spots appear on affected leaves.
