Bud rot 4 weeks out from harvest

If its end of life and its truly bud rot mold it won't do much damage if you strip off some leaves, best to get more air in their and keep the RH on the lower end of the spectrum. Bud rot tends to make the buds go grey and squishy. WPM makes a white powdery layer over everything. WPM is a bit harder to deal with I find, with bud rot you need to cut away all the infected material and dispose of it, don't be afraid to give it a wide margin of error when cutting it out as the mold is tricky and spreads easily. Can spray a bit of hydrogen peroxide to try and deactivate some of the spores but to much will irritate the plant. Best to wash you buds after harvest now, mold spores are everywhere, just waiting to germinate when the conditions are right. Good Luck!
