Then it doesn't sound like too much Ca, unless you're giving them a lot. You could have locked it out with too much P from the Bloom depending on how much you were using.
And since you're in FFOF, you could also just give them plain water until harvest. That soil has to still have some nutrients in it. Whatever you do, I'd try to see if I could keep them alive for a couple more weeks or so. If they start looking worse then I'd chop them. But I'd at least give them a chance to fatten up a bit more.
