It's strange seeing root rot with controlled water temps. In regards to water levels I wouldn't say that was the issue, personally I fill up my system as full as I can get it, usually the pots sit in an inch of solution and right now when I switched to an air cloner to a straight out bath I saw much better rooting in my clones. I think you should start over. Try adding silica to your feed, it acts as an anti fungal, humics and fulvics are amazing too to help buffer a lot of things and kelp extract is awesome too for plant health and defence. I've got this in photos on my current diary here if you want to see what I was talking about.
Raise your pots and you'll see a big difference. Some cuttings just start off rough, yours are saveable.
The plants are hungry but feeding them more now is like asking someone to eat while you are choking them. With the rockwool more dry and properly oxygenated, humidity at least close to 50%, and all rot removed from the reservoir, they will eventually recover and need more food. Most of what you feed them now is just going to the bad microbes anyway.
Honestly
I grow in a humid environment I cannot say much about vpn..... the lack there of, its not a problem I experience.
I can say lower your water level, you have soaked Rw, they don't feed well with rotting roots. Once they tap into the rez u need to be much lower or you are playing with fire.
And your ppms are very low imo, I run 700+ at that point.
As for the 3 inch net pots, I would never grow any adult plant in anything less than 5, I use 6, some can do 4 inch, but I have 2 inch stalks in my dwc, 3 is way to tight for a large plant. Maybe auto flowerscan roll in 3.
+1 for apparent root-rot. I dealt with this on my first grow. Anti-fungal may be too late to fully rescue this grow, but it's worth a shot.
Great! Thank you AquaMan !! I appreciate the detailed response.
I apologize , I’m not sure if I mentioned this. But the ROI720 Light was at 25% for the 1st 10 days, currently its at 50%.How do I determine how much umol or intensity to give the plants at any given time during the grow?
I do have hydroguard on hand. Do you recommend using it? If so how much per gallon? How do I add it to the Rez? Would I then stop the H202? Is there any negatives to using Hydroguard ?
I was running h202 at .5ml per gallon at the start, once I noticed the root discoloration I upped to 3ml per gallon for 3 days straight and then back to 1ml per gallon there after every other day.
I honestly just don’t like the idea behind adding h202 and I’m not well educated enough to make a sound choice behind this. When in doubt, I like to play things safe. I guess ultimately risking a run now playing it too safe? .
Can you briefly educate me on the effects h202 might have on the final product if used a X amount throughout the grow?
Do you consider this root rot as well? What would you say was the main culprit for this if so?
When your referring to top feeding the net pots, the solution that’s used, is that RO water alone?, RO ph adjusted ? Do I just scoop the nutrients from the res and pour a cup or so over each plant? Sorry I’ve never top fed.
I would stop top feeding once roofs are well established though no?
Similarly, should I be misting the plants with water if my humidity is on the low side? If so RO water? PH adjusted? Ext..
The Res PH is remaining pretty stable though this all surprisingly. At the beginning (1st 10 days or so), I was adjusting once every 24 hours with a PH swing of no more than
.8- 1PH. I was adding on average 5ml of PH down total to the 30 gallon res daily.
The last 10 days of so, the PH remains stable at 5.6-5.9 range. I haven’t added PH up or down in 10 days. I’ve only added PH up once, and that’s after the 1st Res change, the PH was too low initially. I added a total of 2.5ml of PH up.
Currently when I add nutrients and top off, the PH is climbing back up around 5.9 and then very slowly dropping again.
5.5 is the lowest I’ve seen in the last 10 days. With 6.0 being the highest.
The lowest Ph since the start is 5.4 when I would add PH down when the PH was rising.
I usually lowered to 5.5-5.6 but a few times it reached 5.4 for no more than a few hours.
PPM has pretty much maintained throughout this whole grow so far. They have climbed and fallen 10-20 points over 24hrs , and then dropped back down and bounced back up from day to day really.
I’ve always ran a few inch air gap between water line and netpot, never any issues at all. At all.
How do you recommend I combat the increased risk of rot from the air gap?
To be Frank, only Top Shelf Cannabis is of use to me. I have absolutely no issue with giving away lbs of entire crops to family and friends if it is nit suitable for me.Sounds a little crazy, but over the years, I’ve developed a very specific taste and need. I enjoy watching and actively growing all different types of stains. But I will ultimately only actual consume very few.
Moral is and Final question, Do you think the overall quality and yield will be effected by this stress if I continue to push through and fight this off potentially?
If and when starting over, what do you recommend I change exactly to reduce the risk of hindering the crops quality and yield potentials.
Thanx again AquaMan! Your time is valued .

H2o2 has no negative effects directly. Its used to kill and keep and bacteria etc good and bad from populating in the system. Nothing wrong with using it.Can you briefly educate me on the effects h202 might have on the final product if used a X amount throughout the grow?

Imo do not miat the plants. Try to get the humidity up bit the light is going to make the issue worse if you drive them to hard in low humiditySimilarly, should I be misting the plants with water if my humidity is on the low side? If so RO water? PH adjusted? Ext..
Lol

Dude, I cant be blunt enough, if you want to grow top shelf herb, maybe you should have spent less money on crap, gadgets, and nonsense. You really need to do the leg work, you might be better off just buying weed. You jumped into hydro and you can't even understand that roots cant be soaked and need fresh air.....top shelf....!!!???
Comon man.... practice makes perfect..
Most of your first grows will be total shit, everybody's are....
This hobby is one of epik phailures and learning. I would take a long hard look at what you want to accomplish. I have been doing this for 15 years and I can say that it's not a quick learn hobby.
You cannot fast forward learning, and if you only want to grow top shelf, sell your stuff to a friend and buy a zip bro!
Its like sitting on the couch eating a twinky wondering why you don't have a shredded 6 pack
Rofl cheers man
You couldn't be more wrong here. The reason I agreed about lowering the water is that with a small root system and much of it in the rockwool it won't get the air exchange it needs and act like it's overwatered. The roots then suffer and rot can set in.. You jumped into hydro and you can't even understand that roots cant be soaked and need fresh air.....top shelf....!!!???

If you ask me this was just a simple improper dosing of hydrogen peroxide. I still don't know the concentration he is using.
Water temps do not cause root rot and pythium as there are several different strains has no issues growing in cool water.
You can run your net pots under water once you have an established root system. Its the transition from cubes, rapid rooters etc thats why you don't soak en. If done in a aqua cloner they can go right into hydroton and fully submerged. Roots in hydo get o2 from the water you don't need them to be exposed. My waterline is kept as close to 1" as possible at all times.
Top feeding is not necessary but good practice. How many grows you see with white hydroton on top? and yea I have seen ppl have issues from it.
The white is just salt build up from the ferts. Top feeding once a week just to keep it clear helps. Like I said not necessary but good practice.I do not normally run h202 throughout. I use it in small amount if I feel the res may be a little less than fresh.
If purchasing clones rooted in rockwool, what do you recommend I do to get the best results? Ive never grown by seed , but hope as things become more stable, that I’ll be able to maintain a setup that allows me to do so more confidently.
I always have white buildup on the clay pebbles after harvest. Normally on the entire walls of the netpot, and also most of the balls are white that are on the outside perimeter.
See my first grow....Do you have any photos of the Rot ?
Did you only change one variable from the time you had the rot, until the time the rot disappeared?
What’s the biggest risk/factor that you’ve found while growing via dwc, or just cannabis in general.
Thanx for your time Nate!
This might sound sarcastic, but it's not: The biggest risk factor is ME!What’s the biggest risk/factor that you’ve found while growing via dwc, or just cannabis in general.
