It's more than uncanny. It's bizarre, it's, it's, I don't know how to describe it

I have had this plant for 10 months and it is starting to grow fuzzy hard white things on top could it just be the bark forming, or a desease?
I think it could be from bugs or over watering I don't know.

I recently replied to another thread on the Forums about this same issue. I'm still hoping to learn more about this phenomenon.
I'll copy my reply down below, and also attach a link to the other thread.

This substance is not scale insects.

Jacaranda mimosifola is known to exude a waxy or crystalline leaf exudate under certain circumstances. I do not know the composition or cause of the exudate, nor whether it is a normal occurrence of a healthy plant or a response to poor health. There are numerous papers available online concerning the anatomy and biochemistry of Jacaranda, but I have not found a scientific description or explanation of this phenomenon.
