Well the season is on for you at last. This is what it is all about. I'm so glad that you are finding a few that you like and will be on your grow list again. I too love Black Cherry and GGWT and ISPL.
As for your Mat-Su and Taxi, they have powdery mildew and probably gray mold too. What I do is to use Bill's bleach spray and then follow up the next day with either copper spray or daconil.
