Is this one a lost cause?

i think i'm on your wavelength. there is a system failure somewhere that's causing this recurring issue. hydro isn't this hard.

i've helped sven in the past: time to stop using band-aids and fix the core problem(s)
 
maybe @J232 was going here, but i think you are sucking something in to your res.

remind me again if you are using RO water?

and for the shock, buy a cheap scale. mine was $30 and it's accurate to 0.01 grams. i'd keep using shock vs tea or bennies.

I just went threw it, it was the air quality going into the water via one pump in my res and possibly one waterfall. It took me 2 months to figure out, It’s not rot it dead root that might be rotting, why shock don’t work, why bennies don’t work..

I’m not saying the situation is the same but trouble shoot everything. I made a bunch of changes so I had to go backwards, when I reset and had no results, I went further. Once you fix the issue, you will be ok.

i've never heard of this in all my time here but how about a tainted bottle of nutes? i'd hate for sven to throw out all his shit. lol

That’s exactly where I’m going, I just about started using someone else’s water...

Op, you smoke heavy or have a air freshener spraying the air, anything like that. If so, try running a garden hose off the air pump inlet (assuming it’s a bigger one) and pick some better air, see if those leaves perk up. Those roots are prob gone but it would of already started some new ones in the basket.

If your cube is high in the basket, run the water higher, if you set it low, run the level lower. Guys say 1.5” or 2” I start closer to 1/2” 1” so it’s just depends. I set my cubes high in the hydron, easier to control a young root.
 
It's kinda RO water - I'm using zerowater filters which literally filters to 0-3ppm depending on filter age. I use the same RO water in humidifier, which has had me wondering - I think it's my last potential contamination point. It's a 5.5l res and if there's 0ppm and no sterilising agents in the water, that stuff's sitting in a warm tent all day. Gets through about half a tank in a day, and I'm only letting it run completely dry once a week for a clean. I have an output fan and since I'm vegging I have no CF on the end of it at the moment. The air is getting replaced in the tent around once every 6 minutes by my calculations, and it's only a small plant. It's also a small tent, meaning wherever I position the humidifier or the fan, at least half the humidity generated is always blown directly to the plant... my theory was that the positive pressure generated by the pump into the res would stop amything contaminating the water, but maybe contamination is via the stomata? I've got a hygrometer sat next to the plant so I know that setting the humidifier to low output and 45% humidity, the plant on average remains at 55% humidity.

I have a small piece of filter in the pump which is cleaned and anti-bac sprayed weekly, and I vacuum the lounge twice weekly. All of this leaves me thinking that the use of humidity is the final weak point.

I'll never use a Heisenberg tea again - it's intensified the problem so quickly it's unreal. But filtering 5 galons through a zero water filter takes forever, and I don't see the point in wasting the time or the nutes if this plant is now completely passed it.

Like I say - I've tried everything now. Sterile, bennies, heisen-tea... silicon and additives vs raw nutes only, and the outcome never changes. Feels like it's time to give up on hydro (or DWC, at least). As you say... there's something off in the environment and I just can't figure out what it is.

I went with DWC for speed, but like I say - if I'd just gone with soil in the first place I'd have had at least one good crop by now.

stick with it!! please!!! you'll never even think about dirt after 1 grow.

like we're getting at, there is something in your enviro that is causing these problems. buy a scale, keep using the shock. 0.50 grams per 10 gallons water is max dose. use that til you got it fixed then drop back to 0.30 grams for maintenance.
 
Fuck it... I'm going to clean the roots in a SB Roots bath first thing tomorrow, change the res... run pool shock alone at 5ppm first for 12hrs, then add nutes. Aftrer a couple of days I'll dose 2ppm pool shock daily. Seriously, even since the pics this morning the roots are just pure brown sludge now. If I see even a handful of pearly whites within 24hrs she's a keeper... if not, I'll start again, maybe buy fresh nutes too from my local hydro store (may even try the powdered a/b formulas this time), and sterilise all water that goes into both the humidifier and the res.

Think I'll use the 5 way splitter that came with the 25w pump and go with 5 small air stones rather than 1 big air disc too (it uses 8mm hosing, kicks out a hell of a lot of turbulence under the net pot and it may be a bit much when the girl's still a fledgling). I'm going to buy and place air filter material in my tent intake ducting too... then that's literally everything I can do to ensure everything is sterile.

You're right - it's a process of elimination, and I quite clearly need to take every possible step on the next run. I can't think of any other potential loose ends.

I just want something to smoke - haven't bought any in 6 months now - that was my equipment/nutrient/additive investment. I vowed not to smoke anything except my own from now on and at this stage DWC is still the quickest route to possessing even a small stash in the shortest possible time. If I can resurrect what I'm working with it'll happen quicker still - I just don't have much hope at this stage.

I'm usually a smart guy and a good problem solver. Feel like an absolute loser that I've been experimenting with this for 8 months and I still have nothing to show for all the time, research, money, thought and emotion I've poured into this.

Light leaks?
Rez temp looks good
Air stones good
When you ran sterile, it wasn't clear in your post, did you add the chlorine just to clean and sanitize, or did you actually run the plants in water with chlorine?

Be sure everything is light proof

I chased goopies for a month... Ended up light leaks in the lid of my tub

Ya just never know

Yup - I have a thick black 45l res, covered in silver bubble insulation, and I silver tape foil round the edges of the net pot to ensure no leaks. I have a small hole drilled which just fits the temp sensor and air hose into the tub, and that's been wrapped 6 times with electrician's tape. Of all the potential issues, I'm confident light leaks isn't one of them

When I ran sterile, I did pool shock daily (0.03g for size of res I had at the time)... after that was a PITA to manage, I bought silver bullet roots. SB Roots is H202 with silver ions, the silver ions extending the effectiveness of the H202 from 24 hours to up to 2 weeks in veg, and up to 1 week in flower.. I've never actually made it to the flowering stage in my journey thus far.
 
Now I have a bigger res, it doesn't seem quite so cumbersome to weigh 0.1g pool shock vs the 0.03g I had to measure last time I ran with it. There's a little more flexibility if I'm +/- 10% of target weight of pool shock now

Okay, well that's good and all, but sounds over complicated. did you ever try just dropping a few drops of bleach into your system while the plants are growing? Lol

Pool shock is what I was recommended, and as weird as it sounds, I always struggled to find Bleach that was just Bleach. In the UK it always seems to contain fragrances/parabens, non-ionic surfectants and thickeners.
