Musty Michigan

These Ladies are in bloom with popcorn on alot of the branches. Some branches are getting heavy with frosty Nugz but half of the plant is flowering at a slower pace. I noticed some powdery spots on some of my leaves this week. After some research I've decided to seek advice from the GD community vs relying on my own experience or trying methods that may negatively affect these beautiful plants. Feel free to chime in 🤔
