Brown spots on leaves, discoloration
I left town for a few weeks and in the meantime my plumeria (watered by my roommate) has lost most of its leaves. As the leaves drop off, they develop soft brown spots. The tissue feels flaccid. I recently moved the plumeria to another pot hoping it has just outgrown its other one, but it's still losing leaves. The edges of its healthier leaves are black and dry. Could this be some sort of fungus?
Please help. This plant is my baby.
