Honeysuckles really don't do well in pots. They're woodland plants that like a cool deep root-run in the shade and their heads pushing up through the undergrowth to the sun.
When in pots above the ground the soil and roots get warmer than if they were planted in the ground, and they are frequently drier too. This makes them susceptible to powdery mildew which is what I suspect is affecting your honeysuckles.
Which way does the wall face, what size pots are they in and what sort of compost?
