I have read many articles on the use of PB and have seen many differing responses. Can you spray the mixture directly on the flowering buds? I use a mix of 1 TBLS PB to 1 TBLS Castile soap to 1 Gal h20. Sorry if this has been covered, butI need someone who has used this mix successfully on budding plants.
Peroxide is safe and extremely effective.

On buds?
Yes. Peroxide is not a solvent that will harm trichomes.

I have the same issue. Posted the same question yesterday, and tried there suggestion of 1:1 3%peroxide:water. Spot sprayed bud areas, and seems good.
I think they saved my grow!!
Just bought another litre of 3%peroxide today.

Thank you for your reply, I have used h2o2 before but at a much lower ratio. I will try the 1:1 ratio in a spray bottle. I have washed my plant, once cut down, with 8oz h2o2 to 5 gallons of h20 and was pleased with the result. I was just worried about spraying fully budded plants as I have 3-4 weeks to go in my northern climate which could be cold and rainy.

Im in the same position.
Hoping to cross the finish line with minimal PM, and bud rot.
Always a challenge up north.
