Nitrogen deficiency

Growth dwarfed; foliage pale green and older leaves yellow and die early.

Phosphorus deficiency

Growth dwarfed; foliage dull bluish green, older leaves yellow and die early.

Calcium deficiency

Death of growing pointt and tips of leaflets of younger leaves. (cf. Plate No. 240, boron deficiency)

Calcium deficiency with high potassium

Death of growing point; bushy habit of growth, leaves bluish green. (cf. Plate No. 236, high sodium)

Calcium deficiency with high sodium

Death of growing point; growth tall, vigour greater than with high potassium, Leaves medium green. (cf. Plate No. 235, high potassium)

Magnesium deficiency

Older leaves strong intervenal chlorosis beginning near margins.

Potassium deficiency

Growth squat; leaves curled backward, dark bluish green color, develop slight marginal chlorosis followed by brown scorching.

Leaflets dull lustreless green with chlorotic marginal bands. (not to be confused with chlorotic bands on self-blanching varieties)

Boron deficiency

Stems and leaves distorted; stems, splitting of epidermis along vascular tissues ("Stem Crack"); crown leaves dwarfed, develop brown areas and many die out. (cf. Plate 234, Plate 235, Plate 236, calcium deficiency where no stem cracking)
