heres more pictures of it

It looks scarred where its browning. Maybe damaged in the car whilst moving? And overnight developed browning round the scars?

I see this condition indoors more than outdoors. If it was outdoors I would say some kind of sunburn but usually that is a solid patch, not round circles.

Typically I remove all the affected leaves and in a few weeks new leaves will come on.

It could be fungal so removing the leaves will help stop the spread and to add a little insurance against future outbreaks, spray with a safe fungicide.

Check out Botrytis blight as this might be the culprit.

Thanks. I’ll remove the affected leaves and see how she goes :) and I’ll have a look for the fungicide too
