The After-Math of Slight Root Rot. What to do After?

So I've been combating slight root rot and I think I have gotten it pretty much taken care of (I think). I reduced nute concentration, have been adding hydrogen peroxide to the reservoir, and added an air stone to my waterfarm. My question is when can I start adding beneficial's and b vitamins back to the reservoir? Is it too early after a week of combating the root rot? It wasn't bad by any means. Just apparent that it was starting to form. Res temps don't get above 70. I'm at 1/2 concentration for nutrients (AN basically burns the shit out of your plants anyways with their feeding schedule and gave me root rot from over ferting in the first place).

Thanks,
Tmac
