Root Debris in DWC. Lots of it. What is causing it? How do I fix it? I don't see root rot at all. It's not really as dark as the picture.

Why am I getting so much root debris? The pH is always fluctuating and I can't get it to stabilize. Is this the cause of the weird root debris? My other plant isn't doing it with the same mix and same pH swings. I don't see root rot anywhere. No slime nothin. Just light brown.

Yes, organic material rotting in your water can definitely impact pH. I'd skim it out as best you can... just add it to the list when you clean/change out reservoir. Some sort of agitation is occuring one way or another..
Poorly buffered hydro fertilizer will fluctuate more wildly, too. Using RO water can exacerbate it... less solutes, more easily swayed... but again, properly buffered products shoud mitigate that.

Root problem or not?I would like to know if this discolouration because of the clay pebbles sitting constantly in the DWC pool and colouring the roots or from nutrients or is this a root problem? There is no slimy thing or bad smell or stunt growth which can be detected.Week 1

Roots getting brownMy Ph probe didn't work, PH was at least more than 0.30 (maybe 0.60) than displayed. As a result they had multiple chlorosis, now septoria leaf spots and possible Pythium since the roots are getting brown. What would you do to save the crop ? Adding mycorrhizae? Thx!4y ago

Root rot?Roots are brown but don't feel slimy and give off no odour. New root growth is virgin white. Could it be discoloration from the nutrient solution or is it the dreaded root rot? pH is constant 5.9-6.1...I added 5mL/gallon hydrogen peroxide to be safeWeek 5

Root rot even using a little water. Can't help It!In my second try I still had troubles with root rot by overwatering issues. This time I waited even 3/4 between waterings (half liter for plant) but soil never ever dried properly. Next time I'll use Light mix, grow shop pots and practice patience. What else do you advice peep?Week 16
