Cannabis is prone to root rot not like peppers.This is what your problem is,your water,nutes additives are good for peppers but not cannabis.no no, I have the peppers in separate containers, I'm just saying that the peppers use the same water, the same RO filter, the same fertilizers and regulators, they are under the same lamp, at the same temperature and humidity, containers and EC level are different depending on the age and size of the plants. with hemp in DWC, I start with EC 0.4, so it will be about 200 ppm, but I also tried with other values, EC 0.6, EC 0.8, EC. 0.2, it doesn't help ...
I don’t know man. Perhaps paprika emits some cannabis killing odour lol. No idea never grow paprika.it's the root of my paprika ... I can hydro, I'm not a professional, but I have enough knowledge to be able to grow in hydroponics, I dream that my hemp would have at least half of the roots that peppers have, this package in this photo grew in canna aqua with voodoo juice, no problems, no deficits, not even calmag needed ...
Air quality, are you inI cook stones and clay balls in water, I have never had slime in the water. if to develop the theories about mycosis of the roots at DWC ... why does cannabis stop growing in the ground? biobizz, plagron, canna, coco ...? I think what kills my seedlings is beyond the ground and beyond the water ... it is something other than overflow, something other than a root fungus because these roots do not rot, they stop growing against them. I have one seedling in colorless containers to observe what is happening with the roots, I can see that they are white, they have these tiny hairs which they call air hairs, I can see air spaces in the ground, there is no rot, and yet the plant does not grow, it stands still and it withers the leaves do not even extend towards the light, I did an experiment and turned on the ts1000 at 25% power to make the plant stretch up, not stretch out! she has stopped and is standing.
Same water I have,I have a little more ca/mg in mine.I can grow clones with straight water and 50ppm of calmag.After lots of roots come out the net pot I add food.the plant in the ground was not watered, I sprayed it so as not to overflow it, the soil in the bag is sufficiently moist, it is not overflow, the symptoms are the same as in DWC and it is impossible to overflow at DWC. My tap water has a pH of 7.0 and an EC of 0.2 / ppm of 98
then down the lagoon in a big zipper bag? blacksmith nadikna? I think theirs a bit of a language issue here.I have seeds in original containers, for example RQS gives seeds in blisters, you can pull them out individually, each seed is separately in their packages, Dutch Passion gives these metal containers, never spills seeds, has a hand, only sprinkles one seed so that the rest do not they grabbed the moisture, then down the lagoon in a big zipper bag and into a metal container where I keep other seed bags of packets and that kind, it's a cheap gardener's box. some time ago I thought that maybe they were cheating on seeds, but I bought a total of 3 separate stores and the problem was always the same ... so it's not the fault of the seeds, I had a lot of varieties, seasonal and automatons, old seeds have a problem with germination, for example with with seeds from RQS northern light I had 100% germination, the problem begins after a week when the sprout comes out of the ground or eazy plug cube or cotton wool cubes, it stops growing for no reason, and then it eats the leaves, it looks like a deficit, but it's not a deficit, I blacksmith nadikna in 0.25L and large 9L pots, I sprayed water so as not to drown them.
Good for you man,i think your onto somthing.Look … it all points to the seeds . Whether its your storage methods , handling or even the stock itself.
Seedlings are victim to pathogens. Forget what others do in there grow - your grow area is different.
There is way overthinking in the majority of post.
I would fo full teardown of dwc rig … clean / soak all.
Lines / pump ( spray lysol on it / let dry ) , net pots … everything. Then mist an ISO spray over all before assembly.
Gear done - check
NOW …
If using rooters or cube , presoak those into hydrogen peroxide / watersoak , then rinse them before use.
Are seeds bag or breeder ? ( maybe bad run of seed stock ) , if not … then issue is when you germ and pathogen is introduced.
Your not answering ea question,#1 Do you sterilize the seed?Eventually we will find the problem.It will take some time but answer ea question one at a time.only this does not explain why the same thing happens in the earth? because suppose there is a pathogen in hydro and it kills seedlings ... but what then kills them in the ground? I have a biobizz starter kit, useful bacteria and mycorrhiza, everyone says that on these fertilizers the risnoe plant itself, that the bacteria feed the plant and regulate the pH, these fertilizers did not help me, even in sterile coconut I tried bio tabs with it, I also made a mix of 50 % soil biobizz, 20% perlite and 30% coconut because biotabs need weak soil to prevent over-fertilization, it did not help. always the same problem and it keeps starting the same, never had 20cm of cannabis
