I really like H2O2 for treating root rot and increasing root zone oxygen levels, but it has to be used in the right percentages.
What percentage do you use it at in a res? I've used 8% before to "clean up" the media I keep some of my more boggy plants in (gets algae, mold, etc growing from being constantly wet) by doing weekly flushes with it. But do you think that would be too high for continuous immersion of the roots?
I'm sure that's fine. I think I usually dilute the 35% to around 5ml/gal or slightly more if it's a hardcore case of the nasties.

if im wrong tell me. I only found one person to tell me dulition rate. and they said they do 2-4 percent weekly. 2-4 parts per 100. i trust them. but they could be wrong, which would make me wrong.

We have mildew. Ironically it's only on the clones we purchased. My plants I have grown from seed, nothing. I think they want to use the hydrogen peroxide to fight the mildew and they are on the wrong track.

For powdery mildew you might want to look into a sulphur burner.

Physan20 @ 1ml/gal during lights off. Spray it on EVERY FUCKING THING IN THE ROOM. Every leaf, the pots, the dirt, the walls, the flow hood, EVERY THING.
mildew will be gone by tomorrow morning.
