Magnesium deficiency
Magnesium-Mangel
This description was machine-translated.
How to spot it
With magnesium deficiency, the leaf tissue between the veins lightens, while the veins remain green. Unlike iron deficiency, it begins on the older, lower leaves because the plant relocates mobile magnesium from old leaves to new growth. Tomatoes on light soils and apple trees with heavy fruit loads show this particularly in mid-summer.
Prevention
Supply your plants with magnesium-containing fertilizer or incorporate magnesium carbonate into the soil. This increases the supply in the long term. For acute deficiency, foliar feeding with Epsom salt (magnesium sulfate) as a spray helps. Do not fertilize with an emphasis on potassium alone, as too much potassium blocks magnesium uptake.
