Blackberry leaf problems

mallorynina

I planted a Merton Thornless blackberry back in June which has settled well.  It has a few berries and is sending out long shoots.  However, some of the leaves are mottled and reading up on it I wondered if this could be something serious.  Can anyone advise please?

I think that’s just the onset of autumn ... I wouldn’t worry about it 😊
