My bud rot came from dead plant material, some came from bugs that caused dead material. Brown pistols also was a source..It was the only thing that had changed, and the only spots where there was rot was behind where the bits with burnt looking tips were. May be a coincidence, idk. Hopefully the rest of us will be able to get ahold of the phyter for next summer. I'll be watching the 3 remaining ladies extra closely now though.
