Hi DTouchberry,
I have a possible solution. I talked to a bunch of people (all have different theories). the one I ended up going with was from a plumeria society.
They said it was caused by an insect, which by this point has left the plants (they hit apparently early spring).
They recommended treating with a 3 in 1 (made by bioadvanced now). I mixed up 5 gallon buckets of it, and gave it to all my plumerias, not just the one showing the wierd leaves.
I waited 3 days, and then soaked the plumeria with water (my plumerias never get any water at all).
A week later I soaked them really good again.
that plant is now growing normal looking leaves. The leaves that never formed stayed that way, but the new leaves coming out are all normal again.
