My zucchinis rot on the vine at flower end when tiny babies

Question

Hi. I have tried garden sulpher but to no avail (that’s the white powder you see in the photos). The weather has been hot and sunny but this end rot has happened in past years, as well. My 3 plants are healthy and lots of flower blooms otherwise. They are in a large garden with lots of room. I water well when soil is dry if we haven’t had recent rain. I fertilize with compost before planting and sometimes use a chemical veggie fertilizer later on although I haven’t done so this year.
