added bat guano first day of flowering
four days later it started dying.

Pics didn't post.

Under the "additional options" section, click "manage attachments" and then "browse" and find the pic you want to upload. An alternative is to place the pics on a webspace, and give us a link to the site.

Leaves often fall off into flowering - usually late flowering. They start yellowing from the bottom up, and gradually fall off so your plant will just look like one big bud.
It could be this that is happening, but if not, just flush with a good few gallons of water - not sure how much water youre supposed to use though. Just do it til the water runs clear.
