Budwashing recipe for 1 gallon

So I wanna give my harvested buds a wash due to some PM on it..
but I don't want too use 5 gallons in buckets way to much water for just one plant anyways..

Does anyone have a recipe for 1 gallon of bud wash ? All I see is 5 gallon recipes ..

Do I need to use the hydrogen peroxide or can I skip it an just use the lemon juice and baking soda ,
I noticed that the peroxide makes the pistils die off turn into a dead colored brown or should I go ahead an still use it cause of the PM

.

Southbay I filled a 5 gallon bucket with 2 gallons of warm water and 4 ounces Dr Zymes Eliminator - it digests the powdery mildew while leaving the trichomes undamaged. It's basically citric acid.

I tried H2O2 and didn't have good results with it.
