Garden Pests and Diseases: What\'s wrong with this clematis & dahlia?, 3 by halesowenmum

Hi. I wondered if anyone could shed any light on these two plants and what might be ailing them? There\'s one pic of the clematis and then three of the dahlia.

Firstly the one I\'m most worried about, the dahlia. Planted in a pot in brand new compost. I\'ve got two - one looks like this, the other\'s fine. Some of the leaves (particularly the more tender ones at the tops of stems) are all curly and there\'s clearly been some nibbling going on although I can\'t see anything - there\'s certainly no cluster of aphids, and there\'s no evidence of slugs.

Secondly the clematis - any ideas what\'s causing these lighter green lines?

I\'m in the UK and my garden is north facing.

Thanks!
