It also looks sun scorched to me. If it is on a location where it gets direct light, it should probably be moved somewhere else where it gets indirect light. Hope this helps!
I think it might be sun damage too. Summer sunlight can be pretty intense compared to other times in the year. I try to do a seasonal shuffle with my plants a few times a year.
Thanks all for the quick response, it's not in direct sun. Window is North facing so it's indirect light. Possibly thinking it's damage from travel, bought it at Plantcon.
