As these plants dying?

Hi

I’ve attached some pictures and am looking for advice as they look like they’re dying!

- 2 pics of honeysuckle at the trellis: this was planted back in spring and is growing and flowering, however, you’ll see the leaves are all white and diseased looking. I’ve bought some spray for it but not yet sure if it’s helping. The leaves are brittle and fall of easily when touched.
- 3 pics of heather: these were only planted a few weeks ago and look brown and dying already!! Have I maybe planted them too close?
- 1 pic of phlox: this was planted in spring and has grown but it keeps getting white stems which just fall away easily.

Any suggestions to the above would be much appreciated.

Thanks
