Are they positioned in a window
They've been outside most of the summer, same as always. Then they'll be in the conservatory when the frost starts.
To much sunlight Probally I have some outside also but in shade all the time
I seriously doubt there's more sunlight in Wales than in England. Everything else is the same, except our water comes from a borehole so no chlorine. They seem well enough on it.
No when the leafs start going redy coulor they are getting to much sun there not a plant that is meant to be in full sunlight anyway
