What are your res temps? I get it in veg
What are the root zone temps (if not "in" the res) not sure
What nutes are you using and at what strength ?lucas formula 6/9 for coco
What additives have you added and at what strength. roots excelsior but not helping
What wattage airpump used (if using airstones, etc)
What size reservoir? 40 litre
What water source? tap water never had a problem before now when I water in I can see a film on top of the water please somebody help its doing my m8s head in

I'm suffering the same thing I think, but I dont think its severe root rot, just very unhealthy roots that are tan/brown and all the root hairs are gone. I think my problem has been with not always cleaning the runoff water from the drip trays. If you are not doing that I would definitely start there.
Im currently 3 days into flowering, was going to drench with 1TBS per gallon of 3% H202 and then immediately hit them with some caps bennies and starting brewing up some teas asap. I'm stuck between this and getting some pond cleaner and going the enzyme route.
Does this sound like a game plan and which would be better?

so before I add 22ml a gal is it safe to use on little cuts thanks everyone im off to water them I will post my results
From my personal experience, it is safe. If your medium/runoff stinks, you've got a big problem. I recently saw a video of deep water culture where the guy is using 8ml/gal of 29% peroxide. That works out to 7.7 tsp/gal of 6%, or 38.6 ml . Search Youtube for "DWCers H2o2 Root Stripping For Root Rot." After you get this under control, quit adding peroxide for 24-48 hours and inoculate [hand water] with EWC ACT and/or an inoculant like Great White or similar. Or you can top dress with EWC, hand watered in. You won't want this inoculant runoff to go back into your rez unless you change it right away.
Also, it is a myth that you can't overwater in coco. I've done it. You need to make sure your coco isn't staying soggy. Adjust your dripper interval and/or amount. Spend 8 bucks on a moisture meter to have around. This will let you see if you have the drying interval that Canna suggests for coco between waterings. The coco should dry enough that there is a noticeable difference in the weight [pick it up] before you water again. Good luck. -granger

The effectiveness and strength of hydrogen peroxide needs to be put into perspective.
3% hydrogen peroxide per gallon of water, for example, isn't going to do anything to anything. It won't clean dishes, never mind cure root rot.
I've used 35% food grade hydrogen peroxide at 2ml per L for rooting cuttings in a sealed bag, and I know you can go to 3ml per liter of water for cuts. Maybe you could go further.
The danger is, at a certain point you can oxidise the roots. I don't know how much it'll take to do that, but like med-man I use it on everything and I don't go as far as to measure unless I'm dealing with individual liters of water.
It's really nowhere near as powerful as people seem to think, which would go some way to explaining why a lot of people use it to treat things like root rot and have no joy.
I'd say if you're going to use it to attempt to cure something as serious as root rot, I wouldn't fanny around with teaspoons in a gallon. You'll need at least 3ml per Liter of 35% food grade. If you've only got 3 or 6 %, obviously do the maths and multiply it by that much.
I'd also use bleach after every watering to clean everything the water came in contact with. Any trays that catch run off etc should be cleaned each time. Then keep running with a slightly lower dose of peroxide - between 1 and 2ml per L of 35% food grade - from that point on.
