Gardenia Leaves Turning Brown

In the past it had powdery mildew and I sprayed it with a fungicide and it did well. Recently I noticed the bottom and inside leaves were exhibiting powdery mildew signs again. I used the same fungicide (same container) and it had been stored inside. Now the leaves are turning brown rapidly. Is this due to the fungicide or is something else going on. P.S. I did spray around 6:00 am so it was warm but not hot out.
