Little black things there look like it could be Caterpillar damage causing bud rots.IME, if the bud rot wasn't caused by higher humidity it was pest related. I've heard good things about silica helping to prevent molds and PM from taking hold, but what was your Pest Management?
I move plants in & out to build strong bones. Seeds under the sun are much larger ime.
Caterpillars / cabbage loopers can be a pain. Many times they come from brown moths and are hard to catch until they are large enough from eating your leaves or in your case the buds start falling off because they burrow inside of the calyx and munch away. Leaving poop. Causing the rots.
