What's wrong with my climbing french bean?

Only the one.
The others are fine. Luckily I've got more to go in.

 

Its not looking to good but a bit more info would help us a lot in the picture the leaves look white is that the case where they grow in situ or transplanted if so were the hardened off etc then I’m sure someone can help

 

They were transplanted and were hardened off.
The leaves looked brown/crispy at the edges yesterday and today is in the picture.
I might just whip it out tomorrow and put another in.
