This is Madame Julia Correvon clematis.

Yellow spots on many of the older leaves. Some new growth which doesn't show spots. Potted in a whiskey barrel last year. Potted in peat moss, perlite, pine fines, vermiculite with some controlled release Osmocote. I did keep watered well. I used a little Tomato Tone on it about 3 weeks ago. Hmmm... It bloomed and looked beautiful all season until these spots showed up. Don't have a clue what's wrong with it...

The bottom pic is when it looked nice and the first is just yesterday pic.
