Someone more knowledgeable will drop by at some point today I'm sure
I personally don't think it's a gonner, it seems to be the left-hand side and the small middle shoot that is looking a tad poorly....the lower section and the right-hand side look quite healthy.

, best wait and see what the others have to say
Hopefully someone will be able to identify it for you, then you will be able to research into it's care and find out about how to treat problems that it may be prone to
