If you are only treating for broad mites and have large plants, heated air makes more sense than hot water. But if you wanted to treat for both broad mites and nematodes (about ten different) 111 degree water is listed as effective. Different sources list different temperatures for hot water but all I've seen caution you to use a test on a small sample to see how they tolerate it. Would you call your single treatment with hot water conclusive in and of itself without trying other temps? I guess I can understand if your only using large plants, but for cuttings 111 degree water is a no brainer for me. Ideal for starting mum mom's free of b.m.'s and nematodes.

Not normal
Most of the buds do foxtail a bit, but these seem more knuckly and grew more round like a gorilla knuckle. Only 1 plant of 5 under the light did this, the rest are normal, in fact a lot bigger.
Normal
Have not cut the normal looking ones yet. They are all fed the same and silica used the whole grow.

If it's the same guys that own the Los Angeles 'cloneville' than yeah those plants are duds.
The pest that causes dudding (IMO) is nematodes which are microscopic (even smaller than Broadmites) and hide very well.
I would ditch the cuts, pop seeds, and select my own moms if I were you. Good luck man.
i would agree that a handful of anecdotal positive ids amounts to not much more than a rumor. only two of the photo-documented. however, the pics did convince me along side the description of the dd's life cycle and behavior. it was an impressively elaborate hoax if its fake. lol. not that thats the only way it could prove false. groups of people can get stuck on a wrong answer, as we've seen, yours truly included.
the main dilemma im seeing with proving this is or not is no one is showing up with any tests. theres been a small handful reported on here all were negative minus a few root diseases.
has any one tried ridomil gold as a treatment and had it still persist. im guessing it has but i thought id ask. the idea that this could be more than one causes or groups of causes cant be ruled out.
im wanting to see more tests from folks.
it seems like the most likely of currently known or assumed variables.
chitosan asprin and kontos sounds like they are working. the first two of those acceptable on organic and the third at least acceptable by current standards here in the states on vegetable starts.

the asprin is a curious one to me because its not water soluble. wouldnt it just percipitate out.
Storm did you use crab shell for the chitosan? Did you put chitosan in the soil? I searched your post but didn't see the exact substance or way of application.
I now have insect frass and powdered crab and lobster shell to put in the soil.
I also have nemastop for root nematodes and actinovate for fusarium.
Am I on the right course?

.5 grams to 5 grams a gallon... drench and foliar
Thanks whatthe215. The cloneville in Seattle says they are sister to the cloneville in cali so they may have the same cuts not sure. I did chop the 3 that were looking ugly but 4 are perfect so I'll keep an eye on them.
The three that were ugly were the GSC, the sour diesel and the white fire, those got chopped. I have a real stretchy star dawg a more indica XXX OG and a snoops dream that are growing real fast and don't seem to be affected at all.
Aspirin IS water soluble.

Stem nematode counteracts plant resistance of aphids in alfalfa, medicago sativa.

Abstract
Plants are exploited by a diverse community of insect herbivores and phytopathogens that interact indirectly through plant-mediated interactions. Generally, plants are thought to respond to insects and pathogens through different defensive signaling pathways. As plants are selected for resistance to one phytophagous organism type (insect vs. pathogen) in managed systems, it is not clear how this selection may affect community interactions. This study examined the effect of nematode-resistant varieties on aphid (Acyrthosiphon pisum) suppression, and then determined how infection by the stem nematode, Ditylenchus dipsaci, mediated ecological effects on aphids and on plant defense proteins. Four alfalfa (Medicago sativa) varieties were selected with resistance to nematodes only (+,-), aphids only (-,+), nematodes and aphids (+,+), and susceptibility to nematodes and aphids (-,-). Field and greenhouse experiments were conducted to isolate the effect of nematode infection and aphid abundance on each variety. We found that varieties resistant to nematode, regardless of aphid resistance, had the lowest aphid counts, suggesting possible cross-resistance. Aphid abundance, however, increased when plants were exposed to nematodes. Resistant varieties were associated with elevated saponins but these compounds were not affected by insect or pathogen feeding. Concentrations of peroxidases and trypsin inhibitors, however, were increased in nematode resistant varieties when exposed to nematodes and aphids, respectively. The patterns of plant defense were variable, and a combination of resistance traits and changes in nutrient availability may drive positive interactions between nematodes and aphids aboveground.

barely, to the extent that it practically isnt. correct me if im wrong but thats what the literature i read says. S.A., and id guess aspirin too is soluble in certain solvents as whatthe215 mentioned already. my question is when dissolved in solvents does it then percipitate out of solution when the ratio of solvent reaches a low enough ratio to water like when you add it to rez. how do people keep asprin in solution a slurry used immediately would probably work but just added to a rez im imagnining it would fall out as soon as you stopped agitating it.

Are those the same as the UC Davis tests that confirmed TMV in cannabis that never saw the light of day?
There haven't been any tests confirming stem nematodes at all. Just some straight up lying going on now. Not surprising.

I mixed it in the res and let the pump cycle right away. there still was a buildup of it on the bottom of the res. Once a day I would stir in and cycle the pump to infuse some of it and make sure the plants were getting a little every day.
