Why are my outlet and switch plates bowing away from the wall?
It appears the wall cannot dry out either to the inside or the outside. I question the use of closed cell foam in the wall and do not think you should add still more without careful consideration.
You built a superinsulated house that was strongly built to resist hurricane force winds in a warm humid climate. You got a wall which traps moisture inside. The blocking every 4 ft is going to make it difficult to dry the inside without removing all the drywall and the sheathing inside. Then you will have to figure out how to insulate the wall in such a way that it can stay dry.
