(again)
I have two tomato plants-- a roma, and an heirloom patio plant. My romas are doing fantastically. But the heirlooms are almost all getting blossom end rot. I googled, and I ended up getting a lot of tips on PREVENTING but not much on correcting it. The stuff that is for correcting is more geared towards tomatoes in a garden, and mine are in a pot. Does anyone know if there is anything I can do now, or is my plant a goner?

Everything the light touches is my kingdom.
