London, United Kingdom

Any idea what this means?
This is uva fragola
received by mail order about 8 weeks aho
was potted on about 6 weeks ago (compost mostly leafmould and kitchen compost).
had grown from its 3ft on arrival to about 15ft in a month
cut it back to about 6ft about 2 weeks ago
lives in a conservatory
suddenly in the past two weeks has developed these dark and chlorotic blotches, and dry parts on the leaves. Could it have been overwatered? or is it a disease that has been tranferred to the plant during pruning?
