Treated my girls for Root Rot.

Hello everyone,
This is my first grow and it's looking like it's coming to an end. I started with 6 seed and 5 of them germinated. (2) Fruit Punch, (2) Pineapple Chunk and (1) King Kush.
I purchased to 50 watt induction bulbs; they were crap, and my grow went extremely slow. So I purchased 400 watt Sun system and things finally started to take off. I setup my grow closet without proper ventilation and temp control and I believe that to be the source of the rot, so anyway. I read up on the issue, constructed an entirely new system, air conditioner included and transplanted my girls. After removing the damaged roots and treating the remaining roots with 3% peroxide. I put them in fresh hydroton and new systems with 2 tablespoon of 3% peroxide in one gallon of water and half strength nutes. Now all of them are dropping and look like they are dying. Has anyone ever treated with peroxide and had this reaction before? Please all opinions and comments are welcome. What are the chances of my girls surviving and recovering? What can I do?

This morning I gave the girls about 4 hours of light and let them rest another 4 hours; I'm happy to say they're perky as every! This grow has been a great learning experience so far!
