Deficiency of Manganese
There is probably a deficiency of Manganese. Manganese-deficient plants usually exhibit varying degrees of interveinal chlorosis, accompanied by interveinal necrotic streaking on the newest leaves or leaflets. As the deficiency progresses, the necrosis becomes more extensive and new leaves may emerge frizzled or reduced in size. Leaves do not become totally yellow, which differentiates a Manganese deficiency from Iron deficiency. Death of the plant usually follows quickly if not treated. Manganese deficiency is very common for many species of palms and cycads in Florida, especially when plants are grown in alkaline soils.
Plant is a monocot or noncotyledonous (includes palms, Pandanus, draceanas, yuccas, cycads and others
- Symptoms are most severe on the newest leaves
