HI. I have a plumeria where all my leaves are turning yellow. The plant is blooming with new flowers coming out; however, 70% of the leaves are turning yellow or have fallen off.

i live in Thailand in the plants native environment. It gets plenty of sunlight. I suspect I was overwatering it previously and have cut back to once a week for the last two weeks.

Last week I added wood vinegar to try to stop any root rot. Today I added Epsom salt and a 10-25-6 fertilize.

Any suggestions are deeply appreciated. Thank you.
