Is there a small brach you could cut off and inspect the cross section to see if it is through the whole stem. IF its mainly on the outside you might be able to continue treating.

What happens when you water, does it perk up pretty quick?
If I did that i would have to sacrafice the branch. As far as the plant perking up ill have to see when I water tomorrow!

Be patient and I'm sure somebody else will chime in, but from what I see, the diseased section should go, you'll be losing some buds, but in the long run you may save the plant.
I think at this point I totally agree! Today was the first day it wilted so Ill see what the next few days bring before making the final decision !

Thanks for the input guys!!
