New to dwc whats going on with my roots?

Water temp is 67 degrees using fox farm for nutrient line with ro water. Ppm is at 1300. Week 5 of flower. Please help

Water in the the bucket is about the same color as my roots. First dwc run plant seems to be fine small buds tho

Roots are probably just stained from that caca coloured water. IMO ppm is way higher than it needs to be. Are you sterilising the res at all? And what does the plant look like, if you have a root problem plant will be a tell tail sign

IT COULD BE the start of root rot

Is any of the root mass slimy? Ppm sounds too high, are u using bennies to keep the roots clean or are you using a sterilising agent? If ur doing neither read about sterile dwc, a lot, I’ve used bleach, peroxide, ozone, the whack lol

No slime on the roots she looks healthy. I'm using uc roots to keep things clean

What should the ppms be roughly and what's a good nutrient line for dwc?
