It doesn't affect all the buds maybe 2 or 3 max

Powdery mildew and possibly botrytis.

Grow mold / mildew resistant strains outdoors where your at.

Actinovate is a good product.

I had a sweet looking flower collapse like that and I did an autopsy on it. I found that there was a worm inside. How is your RH?

Use a dehumidifier

After something happened the first time you should have figured out what and why and maybe it would not hsve happened a second time.
I know that sounds completly dickish in txt
but not meant that way at all.
Just saying if it happened last time you could have possibly avoided the repeat.

got to agree with the powder mildew id be looking at rh and temp swings

Bugs. Catapillars. When you see this pull the top off the bud and look inside for the bug. It's there and small.
