Looks like it's had a bit of a tough experience. But actually looks relatively ok.
Maybe just needs some time to chill. It is winter after all.
Also maybe take off that bottom leaf that's damaged and give the others a wipe. Looks like they're a bit manky and maybe not getting full light through?
I got this little guy on offer at B&Q but it seems to be struggling ... it's in a bright spot ... soil not too wet or too dry ... any tips?
bear in mind I am a complete newbie
