Indoor RDWC Grow - Failure at every turn

just now flushed my entire system again.
Ran clean water no nutes for 30 minutes.
Drained and rinsed.
Ran another cycle of ph'd water with a small amount of Pythoff (Chloramine) for 1 hour.
Drain and rinsed.
Now filled with clean ph'd tap water (ppm 140 / ph 5.8 )
I just started to brew a fresh batch of "Tea" in a separate bucket with RO water. (Just great white, 1/2 tsp unsulphured molasses)
I am going to just run plain tap water in the system until tomorrow night, then try adding a tea im brewing at the moment with GreatWhite.
Don't add ANYTHING organic to RDWC. BiIiIiIiIiIig no NO.

Hey man,
Im at a bit of a loss of what to do...
So you dont think I should use benes?
Im not using any organic materials, just the activated benes....
Bro. R/o. Flora Trio. CaliMagic. H2o2 29%. COUPLE DROPS (like 1/gal) of superthrive if you want. THAT'S IT.

Okay.
Im worried though that the roots with the left over bits of rot/algae on it will re-infect my system.
Do you think the h202 will keep it at bay?

Lowes has an under sink r/o system that holds like a gallon and a half at a time for like $150. Buy it. Just get a tote and a vinyl tube, connect it to the new ro spout and just leave it on for a few days to collect in the tote. I elevate mine to where I can put 5 gal jugs under it and installed a spigot in the bottom of a corner and angled the tote to drain to that corner. I basically have r/o on tap. ;)

Are you still using tank/rainwater bud?
Nah man. Ive moved from the country to city.
No more rain/tank water.
I fee like that tank water was like liquid gold considering how well my first grow went ( White buckets + Temps exceeding 96 degrees and no bacterial/fungal/algae problems at all. Pulled ~ 10 OZ from 2 auto plants)
Im even considering driving back there filling up a 60 L drum, and using it as its own "additive" to my RO water back in the city hahahaha.

Hey man, I bought an RO/DI system about a month ago, I used it for my last grow (Which also failed haha).
I used straight up tap water this time and bubbled it for the last 18 hours to rinse the chlorine out. Im currently filling up a 20L container with RO water to add to my system so lower the PPM a tad. I rinsed the roots as you said, and ive got the system flowing with a very weak nute solution (350 ppm).

350 ppm is not weak. That's damn near half strength.

OK I had the same problem in my dwc I started using the hberg tea and haven't had a problem with the root rot since but add a shit load every other day or so to over populate the bad seems to be working well for me I use a gallon of water half a teaspoon of great white 1 tea spoon of molasses unsulferd and 1/2 a cup of ewc bubble it for 24 hours and I use a cup per gallon at first then a cup every other day I dulte that gallon into 5 gallons so it lasts longer works good

Hey man, nah my nutes are very clean. Dutchmaster seem to have very clear water-like nutes. Doesnt really stain.

Where does your air pump set? I read on icmag to only pump into the brain bucket. On the flip side of that I also read you really only need fast moving water. I personally use hydro halos and no air pumps. When was the last time you cleaned your air pump filter? On a side note I have yet to read a thread on Dutch master without the attributes your enduring. In real life I watched a friend suffer the same issue with ebb and flow bucket system utilizing Dutch master. Your base is 150 ppm. Have you had it to a lab? What ec do you run?
Yo.
I have 2 air pumps.
1x 4-Port Air pump at 10 LPM into each site.
1x 2-Port Air Pump at 12 LPM into the control bucket.
Really, everyone you know with dutch master had problems?
I bought AN Jungle-Juice 3 part, which I used last grow and I had the same problem as I do now.
SO I dont think its the nutes per say.

I havn't had my tap water to a lab...its just you're every day town water.
Comes out about 130 ppm, after bubbling for 24 hours before use out it comes down to ~ 110-120 ppm.

I use a mix of RO/DI and tap water. Usually 50/50. So my base ends up being around 50 ppm.
I then PH adjust it to 5.8.
Usually is about 70 ppm after adjusting.
I then add nutes.

At the moment im only running 350 ppm. (Dunno what EC that is)

Didn't realise you could have too much turbulence...

I turned the site pump to just below 1/2 setting, so each bucket is probably only getting about 4 LPM now.

in such high temperature, bacteria and grow in the water and screw things up just as bad as algae. the high heat isn't helping any.
I dont know why people keep saying this...lol
My first grow had high temps and was successful.
Now I have an auto chiller, water temps are generally around 64-66. Never higher than 68.
