Thanks, everyone!  After further inspection, I found worms.  The worms I could see were removed and the yellow leaves and brown areas removed.

I sprayed the plants with BT.  Should they be sprayed again in a week?

It has been humid all summer.  Would you spray them with a potassium bicarbonate mixture to kill the bud rot? 

I hate the idea of losing everything and want to do the right thing to get something useable for my time and efforts.
