Without seeing the white spots you are talking about, it is hard to give any informed information. Depending on the size and look it could be a scale problem or a fungal problem which would require different approaches to correcting the issue. You might want to consider sending a sample to the diagnostics lab on campus ( website for information is: https://pestid.msu.edu/ ) or you can contact the Jackson county office to see about taking a sample for diagnostics over to them. (Jackson County Info: 1715 Lansing Ave., Suite 257
Jackson, MI 49202 Email:email@example.com Phone:517-788-4292) If you can get a good clear picture to send it might be possible to determine the problem from that.
