Very few plants thrive in soil that is always moist, so that may be part of the problem. You may be drowning the plant. It could be bacterial spot, which is prevalent during wet seasons (you see the connection?). It could be a blight, which is a soil-based fungi, but it’s more likely water related. Water less often, e.g., when the soil is dry, and see what happens. Impossible to know if the plants will survive.
