AsNoriuanswered grow question 4 years ago If you defoliate now, every wound is easy access for budrot. You should take all bud down,not part, treat that place with cinnamon and pray for good, if any new places appear , just chop it !!.
Inspect all harvest youtube peroxide and soda bath before drying for protection of harvest, it works !!!
And when all is chopped, you could buy sulphur smoke bombs , leave them inside for 24 hours, ventilate well, don't light in livable area, its poison, but will kill all bud rot spores.
We used it in greenhouses every autumn.
Good luck in lost fight !
