Hello there, I am based in the UK (East of England) Just a quick shout out to anyone who many have any thoughts on what is affecting my peach and nectarine trees (grown in containers) which are new specimens brought in last year. (purchased as two year old plants). As pictured, yellowing of leaves red marks, lesions and blistering. It is an unheated glasshouse close to the entrance doors/windows. The lack of shading in during the summer months is an obvious problem but pest and disease wise if anyone could shed any light on the matter I would be most grateful. Thanks.
