South Bohemia, Czech Republic

Ivy problems - we have recently bought some small pots of ivy from a local garden centre and though most is fine, some of the leaves have a silver-grey sheen. We have planted it in potting composts in a large granite trough.

The discolouration doesn't show up well on the photos though so I am not sure if anyone can make any suggestions as to what might be going wrong. No visible spots or insects and it doesn't look like mildew...

Any help gratefully received....
