Plants are deficient in iron

Symptoms

When plants are deficient in iron, the old leaves remain green, but the new leaves turn yellow, and the leaf veins remain unchanged. Later the leaves turn yellow-white and the veins gradually turn yellow. When plants are severely deficient in iron, small spots will appear on the leaves, and the leaves will dry up or even die.

Apply fertilizer containing ferrous sulfate to the roots of the plants, or spray foliar fertilizers containing iron to the leaves of the plants.

Plants lack manganese

Symptoms

When plants are deficient in manganese, there will be yellowish-brown spots or reddish-brown spots on the tops of the flower leaves, and the leaves will be gray-white. The small spots on the tops will gradually expand until the leaves wither.

Solution

Apply fertilizers containing manganese to plants in a timely manner.

Plants lacking phosphorus
