Root rot???

I am new to growing in a dwc and I am unsure if this is root rot or not. A little back information on the bucket it’s in a 17 gal tote it holds 10 gallons of water im using general hydroponics nutrients the full line Plus Hydroguard, ph is always between 5.8 and 6.2 ppm is right around 900-1100 water is always about 21/22 degrees Celsius. I am in transition from veg to flower, I have been changing light 1 hr a day for 5 days. Any help would be great thanks in advanced

That's the start of root rot alright. Getting the temps down will slow it. Frozen water bottle or ice pack in the nutes but wash good first so you don't introduce new bacteria to it.

I always used 35% food grade peroxide to prevent rot. Just 0.5ml/L or quart twice a week to prevent it but up to 4ml/L daily for a 3 or 4 days to kill what you got there. Can you get any of that or do you have some? Fat chance of getting any on Xmas.

How come the hour a day light change? Just flipping to 12/12 always works best for me.

Good luck and very Merry Xmas!

11X the amount of 35% for the same effective dosage. So with a 10gal/40L tank at treatment levels of 4ml/L 35% that's, 4ml x 40L x 11 for 1760ml/day. 160ml of the 35%. I used to buy it by the gallon but made a DIY chiller and didn't need to use it anymore. Handy around the house.

So 1760 of 3% h2o2 and do I add nutrients with the peroxide ?

Nope. Just top up the tub with it. Should dilute some of it by half and pour through the net pots too because there will be some of the bad bacteria up in there to that will re-infect the rest of the roots.

I would try to score a couple litres of the 35% tho. Hydro stores and most health food stores carry it. I paid $17 for the last litre I got a few months ago up in Grande Prairie, Alberta where everything cost more. You'll need to do it at the minimum every 2nd day for 3 treatments then lower doses twice weekly to prevent it happening again unless you can get the nute temps down to 65 - 68F / 17C.
