I usually spray plants in growth stage with horsetail fern tea to control spores (and since it's 80% silicates it makes the plants very strong) but have had grows where I have forgotten and PM and bud rot appeared in the last week of flower. I removed the couple of flowers affected by the bud rot and spray-drenched the whole plant (and entire grow area) with 250ml 3% H2O2 to 1 gallon water. This removed the PM and prevented further development of bud rot. I harvested a week later and the buds seemed really OK without a trace of anything nasty. I washed them in h2o2/water then rinsed just as an extra precaution. I have sinced used h2o2 several times on buds in the last few days of flower without any adverse effect on taste/aroma/strength. Re bud rot; the couple of times I had it was usually within 10 days of harvest date. On both occasions I removed affected areas and sprayed with water/h2o2 every couple of days until harvest. Despite the high humidity and lack of decent ventilation, I was able to keep the plants rot-free until harvest. Some people seem to think H2o2 is somehow harmful to the plant or buds, but the 3% sold at pharmacies is completely safe when added to water and will not harm plants or affect quality/taste/aroma of buds.
This is how I use H2O2 (I am not sure where I got this so my apologies - and thanks - if it was posted by someone here)
Sprouting Seeds: add 30ml 3% H2O2 to 1 pint of water. Soak the seeds overnight.
Insecticide Spray: combine 250ml 3% H2O2 to 1 gallon spray mix.
Fast growing container plants (not for plants in soil): add 30ml of 3% H2O2 to 1 gallon water.
Hydroponics: apply 3% H2O2 at a rate of 30ml/gallon to the nutrient reservoir.
