That is one beautiful jade--and healthy looking.
This will be just a guess.......
Perhaps the soil is too wet? And succulents do store water--so, if there is
too much water in the system--would it be seeping out through the wound?
If this is the case--allow the jade to dry out completely. It can take it.
Many succulents need not be watered more than, maybe, once a month.
Your pot is large, so there is a lot of soil in it--which = too much moisture.
As I said--this is just a guess.....Gita
