In hydro its also variety dependent. For example I've never been able to get Romas to grow in hydro without at least a few fruits having blossom end rot, but have had great success with other varieties.

I've found that trying to drive more transpiration in combination with a CalMag foliar spray before the first truss starts to set fruit can help.
