just so you know, chlorine is a tertiary nutrient for cannabis. and safe for humans and plants at the ppms you'll be running.

if you want to try something, take a bucket, some water, an airpump/airstone and add molasses to it. check on it in about 3 days and you'll see exactly what you got going now.

i use GH maxibloom, cytoplus and southern ag garden friendly fungicide (same stuff as hydroguard but a million times concentrated of the same strain of bacteria)

FYI pool shock is different from bleach. Chlorine is also an essential micro nutrient for plants. Please research it, but in my experiance it works much better then H2O2.

Not saying you’re completely wrong but I think that statement is flawed.
I’m not doubting you’ll grow some nasties in molasses water alone but saying it will be exactly the same as when you add molasses to a res full of benificial microbes is not true. Also if you reread some of my posts you’ll see I said the res itself doesn’t have any gunk in it running the pure tea water, but only roots in the water is affected.
The whole point of Heisenberg’s tea thread is to breed more bennies than baddies and that recipe uses molasses as feed.
With that said, I’m also not saying that isn’t my problem which is why I’m changing nutes.
My hope out of this thread is to see if anyone knew what exactly this was and ways to combat the slime but keep the bennies. Since that doesn’t seem possible, I’m in the works switching to a more sterile res.

my point with the bennies that i use is that you don't need to feed them carbs, they feed on the bad bacteria. if there are no bad bacteria, they go hungry and die.

That’s why I said bleach or trichloro s triazinetrione which is what non chlorine pool shock is.
Also, like I stated before, I’ve read up on the use of bleach and “safe level” and all that... The not wanting to go that specific route is personal preference, nothing more.
It also goes against my original goal of having a living res instead of a sterile one.

I suppose I'm real confused because no one was talking about bleach until you started to. I would not use bleach is what I'm saying! Bleach is different from pool shock, you want the chlorinated shock, not bleach.
I totally get you wanting to have a living res, and that's what you've got lol. but its the bad stuff living. I'm not saying you can't run organics in DWC, but it really seems like more people have problems with it then it could possibly be worth.
I was just trying to offer what honestly seemed like the best last option. Trying pool shock would be WAAAY less stress and damage to the plant then changing the damn medium out dude. You don't even have to keep running it if you change your nutes, and get everything killed.

Ive seen people mention using bleach and I’d rather not go that route. I guess that’s what I was saying. I’m also not too fond of using chlorine/calcium hypochlorite If I could help it...

Right on man, I get you. I was super hesitant when I first did as well. I have really never liked the idea of the bleach. I had always bubbled my water for 24-48 hours before using it to "remove" the chlorine. So the idea of adding chlorine seemed crazy to me. I tried it on clones first, and they loved it, and then on my main res and all it did was kill the bad stuff that was causing my problem at the time. Since then I use it in the summer mostly when temps are a little higher just to be safe. Good luck getting things fixed man.

Well, I’m gonna change the nutes and run a round of h202 and see if that does it, in the meantime I’ll read more into the pool shock just in case I need to go nuclear.
I fear there is nothing aside from boiling the stones to kill all the bad stuff in there. They are exactly like pumice stone.... can’t hurt trying.
Well, I will keep an update as I progress.

Well, I got my kelp4less nutes Monday. I put in 6ml a gal of h202 and let the drip rings run for 6 hours to hopefully clean up the grow stones.
I pulled the buckets out, bleached them, pulled the air stones and gave them a bath in high strength H202, and sprayed off the affected roots with a sprayer.
I reset everything and then I mixed up two res batches of nutes to about 450ppm added some B vitamins and 3ml of h202 per gal.
I put the girls back and have let them do their thing for the last few days.
Well....
THEY ARE RECOVERING! NO GUNK AND ROOTS ARE CLEAN AND GROWING!!!
Looks like RAW nutes are not the best for hydro even though their website and such say it’s great for hydro. Something in their mix definitely was the problem.
So now I have a crystal clear res and nice new roots coming though. I’m happy to see them finally take off! For having them grow for two months, they are quite behind schedule.
So now here is my new regime.
Kelp4less grow nutes
Kelp4less calmag (part of the grow mix but comes separate)
Kelp4less B vitamins
I did find it funny that even at 450ppm I needed to use ph up instead of ph down like I was using with the raw nutes at that level. Of course that would be the case because I had just ordered a bottle of AN ph down and since that stuff is super strong, Im sure I’ll never run out for years to come! Lol
Thank you all for the advice and I hope that anyone running RAW in hydro finds this thread and it helps them with their issue faster than I have been battling mine.
Y’all rock!
Now, should I start a grow journal? Anyone?

This is exactly why I will never bother with hydro, too much of a pain in the ass.

This is why I love hydro. Lol.
I can add or remove anything in the system and get almost instant feedback and results.
I’m not bashing dirt or any other grow style, I just like the science and I am impatient.

So I'm trying to switch from H2O2 to Calcium Hypochlorite but seem to be struggling with concentrations. Note the grams of Ca(Cl0)2 is adjusted for the Burnout-73 being 73% hypochlorite and each molecule being 72.9% ClO- by mass, which, from what I read, is the PPM you want to measure.
Here's my method: I add 5.5g 73% Ca(ClO)2 to 1 liter H2O to give me a 4000 PPM ClO- stock solution. I'll then add 80ml of that to my 80 liter res to give me 4 PPM ClO-, correct?
The peroxide worked great, but is 10x the cost of burnout, hence my desire to switch. Problem is I've had 2 plants die inexplicably after switching so I assume there's something wrong with either my understanding or my calcs.
TIA.

i measured it out per application, not a stock solution.
with hth (62% cal hypo, i think?), 0.30 grams per 10 gallons water is 3ppm.
i'll let you do the calculation, but maybe 0.25 grams would be 3ppm as a guesstimate.

Okay. Thought it would be a good validation of my understanding if I worked out your PPM. A bit messy, but it works out about right. Look right to you? Please let me know if I'm off somewhere.
10 gal = 37.9 liter
= 37900 g H2O
0.3g / 37900 g
= 3 g / 379000
= 1000000/379000 * 3 g / 1000000
= 2.64* 3 g / 1000000 g H2O
= 7.92 g PoolShock / 1000000 g H2O
but it's 62% Ca(ClO)2, so:
7.92 * 0.62 = 4.91 g Ca(ClO)2 / 1000000 g H2O
but Ca(ClO)2 is only 72.9% ClO- by molecular weight, so:
4.91 g Ca(ClO)2 * 0.729 =
3.58 PPM, which is just about right.
So, assuming my solution is the correct PPM (i.e., <= 4 PPM), how else could this stuff have precipitated the death of my plants? Maybe too young? How old are your plants when you start adding hypochlorite to your res?
