If your nutes are at 500ppm and two days later there at 350ppm you need to up your ppm! It works like this, change res set ppm at say 600ppm ph 5.9 run for 24hrs, now if you ppm rise and ph drops nutes are too strong. If ppm drop and ph rises, nutes are too weak. But if your ppm and ph are basically stable then you have found the right mix for your plants.
The way the roots look have no bearing on the subject. Watch your numbers not your roots. If you were growing in soil or cocoa you wouldn't be seeing them anyway.What if your ppm is steady but your ph is dropping but the roots are looking ok
Sup FooDoo, we touch base on RDWC on our last feed3 year old thread

ISo I run 6 uc's some home made and some current culture. I run co2 natural gas burners in some rooms and none in other I have sealed rooms and open. All my rooms have ph problems at some time during there life cycle sometimes in veg and in flower. I still have yet to nail down the exact reason and was hoping someone else's experience could help me. I run low ppm's never going over 900 usually veg 400-600 flower 600-850 running all an ph perfect,zone and cal mag. veg adding big bud and overdrive in flower.
I have a few that have stayed perfect all the way through but its not consistent and I am doing the same things.
I will give a scenario I a 11k 8 site 35 gallon uc that when full is over 250 gallons. I made the water for veg 500 ppm using no ph down it was 6.3 left it alone . 2 days later it was 5.4 and dropping. This room has a 16 site natural gas burner and the room is sealed. Lately the burner has been having trouble starting and sometimes I smell gas. I was wondering if that could build up in there and cause problems. The ph was always dropping. So we unsealed the room added a 10 inch exhaust fan..Also moved the air pumps out of the room too. It seems to have stabilized but not sure if its from what i did.I have the same problem in another room the veg it still doing the same and there is no co2 in that room. I always thought it was from hi ec/ppms but I find that not to be the situation in my case.

Your roots are unhealthy right now n its not adaquate to absorbs enough nutrients which is making the water acidic, this sometime causes your ph to drop, judging from your system n environment, just my personal xperience. Im assuming your roots are either light to dark brown n can easily pick off. My advice to you is try to keep the nutrients at low to medium strength n change the water every 3-4 days. Add H2o2 with every water change. Just try the best u can with this run. Sterile everything on your next run n keep your water temp below 70, preferably stay at 65. Good luck, pythium is no jokeI
I have
I been having the same problem after 4 days the ph drops
In RDWC? Yeeeah, Not so much.Yes and I am aware of that. My point still stands.

9 times out 10 when I notice rapid drops in PH you are having problems with your roots or possibly some rot in your pots. So checking your roots is good. If yours look fine its possible you have some rot in your net pots. Your rez will have a different smell to it. Almost like celery. Get your water temps down and add some bennies.
I don’t know what kind of air pumps you are using but the pumps I use have a spot where in coming air has a barbed fitting for a hose. I run a line from there directly in front of my AC. it has helped keep my pumps cool which in turn keeps my water temps down.
