You're talking about Bayer Advanced All-In-One (just making sure, because Bayer Advanced 3-in-1 Insect, Disease & Mite Control is a different product)?

My observation follows. The "All-In-One" takes 4 - 6 weeks to become effective, usually 6, and then has to be reapplied on a 4 - 6 week interval (usually 4 weeks here). In that initial 6 weeks, I believe that some supplemental fungicide application is needed, at least one, maybe two. Most folks don't do this. By the time "All-In-One" is effective, you have a case of blackspot just waiting to happen.

On the misshapen buds, not sure if the fertilizer is doing it. The fertilizer is 9-14-9. What has the weather been like there?

Aphids just need a strong squirt of water.
