Hi, I need some help. These are pics of some leaves on my plumeria that rooted at the beginning of this year. They are growing like crazy, solid stems, lots of nice looking new growth. But most of the grown leaves have spots of various kinds, I hope you can help tell me what it is from the pics. They get full sun all day and are in a fast draining soil mix. The soil has no problem draining and drying out quickly but it has rained like crazy these past few weeks. There were many days of rain all day solid and no sun. They have been treated with a systemic insecticide and I thought the spots might be a fungus so I have sprayed them with the Safer 3 in 1 fungicide spray twice in the past few weeks and have seen no bugs. Could this be too much rain or a fungus I need to treat better? I think I have more than one issue here though. Thanks so much for any advice.

There are a couple places where the spots actually ended up holes clean through:

This is the worst one, and the only one with a large brown area:
