Rhododendron leaves going brown

I have 5 small rhododendrons in pots all thriving apart from one where the leaves have turned brown. New growth tries to come through but then also goes brown. All pots are in a line, same sun / shade and are watered. Can anyone help please as only had them a short while, from Thompson-Morgan, they were a gift?
