Overwatering can cause BER as much as underwatering can. The knack is to be consistent ... I find that by that letting the top inch of the compost dry out and then giving the plants a really good soak (usually just once or twice a week, depending on the weather) gives good results.
We've fed three times with tomato fertiliser and once with seaweed fertiliser ... starting when the first truss set and then at approximately 10 day intervals.
We've only had one single fruit with BER out of twenty heavily cropping tomato plants, and that's been my experience ever since we adopted this method.
I also find large bucket-sized pots give much better results than growbags.
