Magnesium Deficiency on Canary Island Date PalmThis sounds like a magnesium deficiency. Visible symptoms begin on the oldest leaves and progress upward to the younger foliage, typically a broad light yellow band along the margin of the older leaves with the center remaining green. People are often tempted to remove the old deficient leaves. Since palms remove nutrients from the lower leaves to replace deficiencies, the next layer of fronds become deficient. Treat with a good palm fertilizer plus additional applications of magnesium sulfate (epsom salts).
