Hello. Why do you feel these plant went bad. They look good at the end of their lives. Do you not like the smell? You can always turn this into hash if you feel the plants are bad.
With a good cure these will turn out great. Please don't just throw it away with all the work you've put into it. Try to do something with it. I'm sure your freinds would love to have some free smoke of you don't like it once it's finished. Chuck.
