Looks like Rust to be honest. I should pick off any affected leaves, and dispose of appropriately. Give em a liquid feed.  ;)

turn over the leaves and see if there's something there - I remember having some hollyhocks that went like that, and I think it was red spider mite.

Looks like rust to me as well. It's a 'once you have it, you'll always have it' disease that's carried in on wind. At one time black currants were banned here as they were thought a host plant which were helping destroy the pine tree population. Hollyhocks are definite hosts to this problem. Only thing to do is as said...pick off affected leaves and burn them. And give the whole plant a spray of one part white vinegar to 10 parts water. The acidity should help minimize further infections.

Hmm, I thought it might be called something like that coz rust is exactly what it looks like (if it were something metal anyway!).  all I can say then is poo!  its virtually every leaf but I'll take them off and see what happens before it affects the other two rows (different types of raspberries on those and not yet affected).

I had a lot of rust on raspberries before and interestingly the strawberries never got it, not that interestingly, rust is a rather species specific disease - though these are so closely related - , anyhow complete defoliation helped a lot with those, could just try to mow the lot.

I thought some of my plants were diseased last year only to find next door had used one of those spray things to paint the fence.
