Copper deficiencies causes bluish green leaves which may wither or fail to unfold. Younger leaf tips may be yellow at the edge. Growing tips may form rosettes. Excess copper may cause iron deficiency. Molybdenum, Mo, is essential to nitrate enzymes and for the formation of root nodules in beans and peas.
Molybdenum deficiencies cause yellow mottling and dead spots on the leaves.
In some plants, the growing tips are distorted or killed. Chlorine, Cl, may affect carbohydrate metabolism and photosynthesis. Chlorine deficiencies may cause stubby roots and wilting. Excess chlorine may cause leaf edges to scorch similar to potassium deficiency. A soil test will give a complete and accurate measure of the nutrients in the soil.
