You are very serious, obviously infected with germs. I think the culprit is that you spray water when you have sick leaves and expand the infected area.

First of all: control watering quickly, there is no reason to water it once a day.

In addition: cut off diseased leaves and spray drugs to prevent bacteria and fungi. What thiophanate, carbendazim, chlorothalonil. . . .

Finally: water spraying is to increase humidity. Spray the beads thinly, or around them. Not too much. It would be better if there were no diseased leaves. Remove diseased leaves before spraying.
