Wilting leaves - H2O issue or disease

Hi everyone! I had some issues with possible PM a couple of weeks ago during a stretch of cool wet weather. Treated with milk spray. Afterwards, I noticed my Old Island Indica/Sweet Skunk plants wilting in places. I don’t think that it’s under watering. The plants are going about 5 days between watering. The last time that I saw anything like this was a couple of years ago when a couple of plants ended up with some brown looking rot. It’s only happening on the Old Island Indicas. Any ideas and advice are appreciated.
