2. Phosphorus deficiency: the plant is dark green, the veins of the old leaves appear yellow, and the leaves are easy to fall off.

3, potassium deficiency: old leaves appear yellow, brown, purple and other color spots, leaves yellowing from the edge to the center, leaves are easy to fall off after withering.

4. Magnesium deficiency: the old leaves gradually turn yellow, but the veins are still green and the flowers bloom small.

5. Iron deficiency: the new mesophyll turns yellow, but the big leaves remain green.

6. Lack of calcium: the terminal bud is easy to die, the leaf tip and leaf edge die, the leaf tip often bends into a hook, the root system will also die, and when serious, the whole plant will die.

You can choose to change the basin and apply base fertilizer. Soil rich in organic matter should be applied when changing basins. If it is the peak period of flower growth, liquid fertilizer can be applied, usually once every 10 days.
