Hi all I have a question, I have several box hedges in pots and are doing well except one which has gone brown on one side, I think this might be box blight but not sure if it is how do i rectify this or do i need to replace it.

You didn't include a photo but there are several illustrations of box blight on google so you might be able to confirm whether that's what you have.
If it is blight it might be best not to replace it. You can get very similar results with Lonicera nitida which is worth remembering if the others become affected too.
