Is very rare with calcium deficiency in the soil, so a lack of calcium we can put aside but inconsistent watering causes the plants’ inability to take up sufficient amounts of calcium.
Calcium can only be transported with the water flow up into the plant and is not mobile so that the plant itself can relocate the calcium and if the water supply is in any way disrupted it can cause BER.
At the time of fruit formation if there is too little calcium generates BER, due to inconsistency of water, too much too less.
However, I cannot see in what way Epsom salt would contribute as there is no calcium in Epsom salt only magnesium and sulphate. Epsom salt is also not doing anything for the calcium uptake in the plant.
Too much magnesium on the other hand holds on to calcium and prevents the plant from accessing calcium and the condition worsens rather than improves, so magnesium does nada when it comes to BER.
Eggshell is another myth, eggshell can take up to 4-5 years before it decomposes and releases calcium in a form that the plant can take up, so no quick fix.
Since BER is not due to calcium deficiency, you do not need to add calcium or anything else for that matter but regulate the watering and BER usually goes over by itself. After all, most of the time the first fruits are affected and then it usually corrects itself.
BER often occurs when it may have been very little rain or dry or very wet for a long time, so when the water supply stabilizes, the problem usually disappears!
If you grow in a pot, you have to regulate the water supply yourself!
