Noobed with h202 and fox farm nutes

I'm a noob therefore I am posting this here. I'm in week 3 of flower and like a dumbass added 1 tablespoon of 3% hydrogen peroxide in a gallon of water with my fox farm week 3 flower nutes. Upon further investigation I realized that's a big no-no as the h202 can wreak havoc with organic nutes. Am I totally screwed here, or do you think I'll be fine? I'm growing in soil. Thanks for any input.

flush your plants with distilled water for 2 days. after 2 days add nutes as directed with no other additives and your plants should be healthy and have a good yield
