Disease identification on lilac please
I bought a dwarf tinkerbelle lilac about a month ago. It was doing very well after I planted it until about a week ago. I noticed the leaves started turning brown and curling upwards, though it was still flowering. The flowering has mostly stopped now (it may be done, I'm not sure) and all the leaves are very sick looking, brown and curled and very dry, almost crunchy. Someone said it looked like powdery mildew even though there's no powder so I put some anti fungal spray on it 4 days ago and it's still looking bad. I usually water it every day on warm days. I've looked it over and cannot see any bugs, or evidence of bugs. I will try to upload a few pictures (sorry about the quality, the wind was blowing). Any ideas would be appreciated.
