Here is the recipe, and you can scale it up or down based on how much you need:
5g citric acid
500ml distilled water
10 pipette drops dish soap
Mix well and spray, preferably first thing in the morning before the sun will be on the plant. If not, late in the day so it can evaporate before nightfall but not burn in the heat of the day.
Make sure you get the whole plant as PM can hide between the buds and the branch.
For the record, 10 pipette drops of dish soap works out to a little less than 1ml in 1500ml of water (or .3ml per 500ml)
