Looks like rot. With your set up, it could also just be dirt getting into your res.
Hydroguard to prevent rot, and peroxide to treat it (you'll have to Google the proper amounts). Hydroguard will prevent rot if your res is getting too warm. If you are having real difficulty controlling the res temp and the hydroguard is ineffective, I recommend throwing a few 20oz bottles of frozen water in the res during the hottest parts of the day. Just make sure you really clean the bottles. Good news is this is easy and cheap because once they melt, you just throw them back into your freezer.
As always, keep an eye on your pH.

Thanks for the answers everyone. I am in Aus so it's very difficult for me to get hydroguard. I have Pythoff which is a Nutrient conditioner used to stop pythium (and other root rot). I do not know what it contains, but I assume that is similar to hydroguard. Temps are getting up around 75. I will try the water bottle tricks.

Your plant looks pretty healthy. So not necessarily.
- Are the roots slimy-ish? If so, then very likely root rot.
If the roots aren't slimy, it could simply be nutrients colouring the roots..

Yes it is root rot. You need hydroguard by botanicare. It's a beneficial bacteria that's kills rot root and will have those roots pearl white. Also you can use it as a preventative in hydro. Love the stuff. Also quick tip you need some type of reflective barrier for your bucket to keep light hitting it and keeping solutions hot. Res temps need to be around 70 degrees Fahrenheit. Try some frozen water bottles.

The issue is still occurring at ppm 690, I have been monitoring every 2 days and I am using a product called 'pythoff' as a nutrient conditioner.

Root rot :(I believe I have a case of root rot. Pic attached. I just added Orca in the morning, and noticed orange foam and these roots literally hours later. Water was still under 70 from the res change sunday afternoon. Currently 68.
I rinsed in tap, they look a little better. ;(

Persistent issues - wilted leaves, light-green splotches, brown rootsMy plant has these issues. I've rinsed off the roots in case it was nutrient buildup on roots, which I still believe to be the case. I have given this plant a good amount of nutrients the week before. Does this appear to be a deficiency? Any ideas?
Thanks all for responding5 years ago
