Dwc slime help needed

HELP NEEDED ASAP ! Hi I've been reading through this thread, amazing info , I just need to pick someone's brains, I've been growing for years with no problems until I switched to dwc .. I got the slime due to improper res conditions, i've now corrected these conditions! with a chiller and blocking out all light leaks,
the problem I'm having is the root that where infected have now been removed but not no new roots are growing and the ones that did start growing survived a day or two then They go brown and mushy once they reach about half an inch from the root riot cube that's sat in the net pot
I'm brewing my first batch of tea as we speak , the babies are very little with little to no roots left coming from the cube are they still infected with slime / Cyanobacteria? the system has been bleach a few times but the roots only grow a day or two after I stop the bleach then they go brown.
this problem has now been going for 6 weeks or more?
1) Are my cubes infected ?is this why roots die ?
2) or is the bad bacteria still living in the pocket above the water line ? How to fix / prevent this from ruing this run , I've waited 5 weeks+ with no sign they are growing at All please help !
Also my system is a alien rdwc 18 pot ph no higher then 6 no lower then 5.5 I'm only light feeding a and b house of garden aqua at the mo, as every time I use the amino, roots Excelerator , multizyme the slime appears again
Please help below is the largest plant with the most root left I know it's bad but any help on getting these rooted again will be amazing

Hey I'm sorry about your predicament dwc is funny that way you can go forever and not see any root rot and then bam! Its all in your grill.

People say to soak your cube in a h2o2 solution. But I think that didn't do anything for me what I found was that aqua shield worked awesome I had the same problem new roots dying off.

After I added aqua shield a week later I had mad roots

i have heard good things about dutch master zone but it kills everything in rez so if you are running benificials then it will do more harm than good. I am using it now with good results thus far, i use dyna grow for nutrient and keep a no living things allowed in my rez mindset.

You're on the right track with the tea

Thanks bro I'll give it a try tomorrow

Only the tea might work at this point. If it doesn't, throw away everything and sterilize anything you can't throw away, and start over.

Once you get I tho it is there always you can't kill off your aqua shield levels or it will come back with a vengeance. And you said you got a chiller lower your temps into the 60's that way root rot can't breed.
