Wow...30oz sounds like way too much peroxide to me. Thats an ounce per gallon. I use just 1/4 teaspoon of 3% per gallon about once a week in my ebb/flo rez during hot weather when the rez temps might get up around 75 now and then. I'm pretty sure you burned them and i doubt that the wilted leaves will recover which will ultimately slow growth and reduce yield.

I would have used about 1/4 to 1/2 cup for 30 gal. You dont need to add peroxide unless your nutes start to smell "swampy", or they begin to turn "cloudy", or you see some slime begin to form in the rez. Its a good way to hold the pathogens in check, but its not a miracle solution and you can do some damage to the girls with too strong of a dose. Good luck
