COPPER – Cu

The two most common symptoms is undersized root growth and leaf chlorosis

 

ZINC – Zn

Chlorosis of the younger leaves which in extreme cases could result in the leaves turning red.

 

BORON – B

Spot-like, striped or blotchy yellowing on the leaves will occur

 

IRON – Fe

Dark green foliage, stunted top growth and root growth, as well as leaf bronzing which causes dark brown to purple spots on the foliage.

 

MOLYBDENUM – Mo

Marginal leaf scorch and abscission as found in typical salt damage. Yellowing or browning of leaves and depressed tillering.

 

MANGANESE – Mn

Chlorosis and necrotic lesions on old leaves, dark-brown or red necrotic spots

 

CHLORINE - Cl

Leaf margins are scorched and abscission is excessive. Leaf/leaflet size is reduced and may appear to be thickened. Overall plant growth is reduced. Chloride accumulation is higher in older tissue than in newly matured leaves. In conifers, the early symptoms are a yellow mottling of the needles, followed by the death of the affected needles.
