Not often the case, unless all fruits have it. For me, mostly it’s just that on some very hot days the calcium can’t be transported to the fruits. That’s why you often see it on some of the first fruits too, not enough root system to properly support them yet.
Blossom end rot possibly! Need more calcium in the soil if so! Some tomatoes are also prone to it, unfortunately.
