The reason is that the accumulated water is wet for a long time, which leads to the lack of oxygen in the soil and the decay of some roots.

Treatment: when there are few pests in the initial stage, you can use a soft brush to wipe the foliar bugs clean, or you can spray insecticides to get rid of the insects.
In addition, there is another situation caused by the normal metabolism of Phalaenopsis.
The top and new leaves of Phalaenopsis were normal, but the lower leaves of the plant began to turn yellow. The cause is caused by normal metabolism.
Treatment method: normal maintenance can, metabolic fallen leaves do not affect the growth of the whole plant, or grow new leaves in the later stage.
