URGENT HELP - ROOT PROBLEMS?

In the grow room I have 4 DWC buckets (10 Lt per bucket, they contain 7 lt of water).
The temperature of the nutrient solution always oscillates between 19 to 22 degrees. Currently I am working with the HEINSERBERG method (tea microbes) since while working in a sterile way I had the first problems.
It was working at an EC of 0.7 (max), I am currently working with 0.45 EC to rule out overfertilization but the EC rises slowly even though it is at a low value.
The temperature in the grow room is around 19 to 24 degrees. Internal ventilation is carried out as extraction (turbine).
The lighting consists of 8 leds cree cxb 3590 at 2.4 AMP each. (Currently only 4 are working at half power 1.2 Amp).
I see there are new white roots growing but I am doubting it is the quality of the nutrients I am using as I switched to just tek Grow (grotek) for testing and got a little improvement, although I don't like using this fertilizer bc it has a small organic part.
The pH was always stable between 5.5 and 6.0.
The plants scream for help and I don't know what else to try. I would appreciate suggestions

Some kind of micro deficiency, manganese or iron maybe.
Agreed it’s probably root rot causing lockout.

Run h2o2 in the res and drop the microbes if you can’t keep it clean.

Ok, I'm going to try this solution. I would also appreciate more opinions.

I have been DWC for 20 years and I never cared about microbes and sterile shit. I just throw some Floranova in some tap water and the girls just love it. I'm lazy and have no originality, I just copy other successful growers.

I'd try cutting away as much bad root mass as possible...clean/spray it all down with plain water (pH'd) before putting it back into the bucket.
You'd be surprised how much can be cut off and not cause much of a problem. :)
I might even try a few drops of bleach in each bucket...I usually put a few drop in a bottle of water (1ml : 100ml) then mix it into my rez slowly...my rez is only about 5 gal tho. :P
But if you dont use much it doesn't cause any problems either.
Also when doing the above clean the whole system out and run just plain pH'd water to see how things change...if they do...adjust from there, but usually after a couple days of clean water and clean rez the plants start to get back on track.
Its a good thing your not in flower and have time to get them inline. :)

Have you tried pool shock? There is thread in the hydro section called. Make $2200 worth of clear rez for $4. May be an option not sure if the ingredients is available where you are or can use small amounts of bleach but those roots look pretty bad. You are shooting for 5ppm of free chlorine but you can go higher than that in a bad case like what you got going on. Check out that thread there is some folks that have been using that stuff for a long time. There is also a product called SLF100 I’ve heard good things about it but have no personal experience with it may be an option. Best of luck with your issue

UPDATE
I tried to cut most of the roots as they looked very ugly, I am dosing bleach at 1 drop in 5lt. I will keep the topic updated.

Dude, I need to be honest with you here and it kinda breaks my heart because I can see how much time and effort you have put in but your plant is beyond help. Just toss it and try again. I can help you if you want.

i see 3 things i'd fix:

22C res temps too hot
heisenberg tea is junk IMO. chlorine is much better or peroxide even. sterile is much easier i think in the beginning
nutes with organics in them? nope. can you get GH flora series 3 part?

Unfortunately I live in a hot area and I do not have a water cooler, so it is not possible for me to work at lower temperatures. I live in Argentina, so here those fertilizers are impossible to get.

can you get any 100% synthetic nutrients?

if a cooler is not an option, then i think chlorine or peroxide would be what i would use

That doesn't exist here either, unfortunately this country is shit. I am using rock wool, and above to cover coconut so that the light does not leak.

you would be better off with smooth rocks in your net pots than rock wool and coco. that whole area in pic afther-1 looks like a breeding ground for root rot.
