but you have so many things going on I am hesistant to point at any single factor and say, that's your problem.
with calcium problem, I've looked at pics in problem threads for calcium, have spots yes, but I don't see much as far as yellowing and falling off...that's probably moreso than the spots...the stems get really weak where they connect to the main branch and once are completely yellow you can merely touch them and they fall off..
