Young jacaranda tree issue, pest? Disease? HELP!

[Skeptikalone]

So yeah, I have no clue. It's a crystalline like build up all over the branches. When scraped it almost seems like it's part of the trees tissue because it is green and wet under like I've dug into the meat of the branch. I had an issue with aphids (nothing crazy) and fought them for the past couple months while they were outside this summer. Brought them in 2 weeks ago and found this today.... Please help, any advice is appreciated! Thank you!

Purple pictures and out of focus pictures and not a close up are useless

Sorry about that! Stupid purple grow bulbs. These are best my camera will do will a white led spot light on it. Any ideas?

I looked at a spot under a pocket microscope and it looks as if it's a growth from the tree of some kind and has a muscle tissue look to it almost, like striated globs all together in the clumps.

Not close focus but shows how it's all built up along branches.

Your latest pictures are out of focus but from what I can see I think your plant is infested with hard scale insects. These insects are permanently attached to the plant and after they are killed will still be there for some time but will eventually fall off. These are sucking insects and if not eliminated will severely affect the health of the plant.. To kill them spray with neem oil once a week for 3 weeks. If you could get a focused picture we could tell for sure.

Your latest picture just showed up. Too far away to tell for sure but it looks like hard scale.

Yeah I tried so hard to get a focused picture and idk if there's just too much going on in the canopy too allow a focus on it but it just won't do it. Then the flash just makes it a glare because it's white. I have neem oil concentrate so just make a mixture with water and Castile soap to emulsify then?

I have never used the soap but I don't guess it will do any harm. It might be a good thing.

I think they are scale insects too.

This substance is not scale insects.

Jacaranda mimosifola is known to exude a waxy or crystaline 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.

I agree with Marck. We get that here mostly in Spring when the humidity is high and temps are warm-ish.
