I'm enjoying my first venture into hydroponics, growing tomatoes, peppers, and basil in a DWC system. All was well until I added 1 cup of 3% H2O2 to the 6 gallon reservoir yesterday. Now everything looks good except the toms. which are droopy and limp at the tops.

I'm waiting for them to "shake it off" since it hasn't even been 24 hours yet, but wondered if anyone might have any helpful tips. A web search didn't yield too much info about the effects of a peroxide overdose and/or selectivity to tomatoes.

Thanks!
