Help - White stuff on tarantula sling

[vuvuimp]

Does anyone know what these white parts are on my sling? On the left upper legs where it connects the legs to the carapace. I'm thinking it might be a mite or fungal infection mabey. There are mites in the enclosure but I don't see them on my sling often. The slings about to molt soon hopefully shed that white stuff. Any insight is appreciated!

It almost looks like poop but need more info.
Does the white stuff move?
Has your t's behaviour been different in any way since you noticed the white stuff?
When exactly did you notice the white stuff?
What does your spood food eat, is there any chance it could be spood food guts?
All this info could help find what this is.

A better pic of the white stuff would help to .
