As long as you re-innoculate after every use of hydrogen peroxide you'll be fine. As an unstable molecule (H3O) hydrogen peroxide breaks down quickly, you'd easily be fine adding it the next day, depending on how much you use it should be fine a couple hours later. It's kinda running in two different directions though, one of the purposes of applying beneficial microbes is that they out compete pathogens and protect our plants. So using hydrogen peroxide does the same thing but in the opposite manner, by killing all life and making a sterile environment. Generally people choose one or the other as they're counter productive to the other.
