i have a few ideas that may help that i am implementing ..
calcium phosphite drench at the root crown has been harsh but seems to be clearing the plant of any pathogens , this was recommended by a crop science specialist here in ag country for battling the disease on outdoor plants . so i am starting the use of calcium phosphites to try and grow through this problem on a few plants that are really sick just to see if it works as suggested.

every outdoor plant i have seen in the past few years that starts having issues can always be tracked to the soil crown at the base of the plant of where the infection begins .. and every single one of them used the same cloning media ... rockwool cubes

take a rockwool cube and rub it on your arm and watch what happens ... rash and irritation!!! as the newly rooted cutting blows back and forth from air movement the stem at the base is being rubbed raw and it is at the point i believe we are getting the problem.
this is just a theory at this point but it is what i have witnessed personally over the past few years ..

for the people having bad dud issues could you please post what cloning media your using to see if we can find a possible problem point ?

Yes, Rockwool is like fiberglass but only when it's dry, when its wet, it's pretty soft.

Overly wet rockwool is not much different than stagnant water, thats when fusarium could kick in. It's airborne, all it takes is one microscopic spore.

I have always used grodan wool 1.5 individual wrapped blocks, I did try rapid rooters thinking that might help and it was way worse so I went back to wool.
I really see it happen when the moms start looking a lil off. Not to say this virus or what ever it is already exist in all my stock but I did mark the cuts that for sure looked like duds and was rite on point. The others that only show a branch or 2 happen later in flowering, I would much rather keep moms but am at the point of and realized I've been beating the odds by taking cuts off a vegging crop that shows no signs and then starting moms knowing that I'm only really Gona get 1 or 2 rounds of cuts off moms = maybe 3to 4 month life span for moms or 2 to 3 times of cuts off her then she starts throwing dud branches.

Sad actually cause I used to be able to keep moms for dam near a year or so as long as the occasional step up to a bigger pot happened. Never had an shit like this happen back in the 1990s or 2000

ive been growing on and off for 20 yrs.... i have never seen or heard any of this dudding from my boys in those 20 yrs.... until now this yr it happen to me with a cookie strain i noticed it wasnt as lush as the other plants but i needed to fill the table space so i jus added her.. i had noticed the soil wasnt drying out like my other girls then i started to noticed the small leafs in week 4 and she was looking sad no thc frost or dank cookie smell i did notice a few bean sacs soo i pulled them off and saved them... i tossed the bitch cuz i didnt want to deal with larf... now a month later and this thread started up.... i think it was just a badly rooted cut and that i kept in a solo cup to long root bound and stressed... i admitt ive used avid and a few other chems as prevent main. but that was over a yr ago...

Whew my head is spinning lots of info to soak up and its all is sounding quite familiar with what is going in my world .
1) fusarium - a def possibility
2) cloning practices and gel - also possible
3) funny that @obsoul33t mentions rockwool cubes as this started to take effect after i introduced 2 rock wool cubes to my kloner
4) temp's - thinking the mid 80 days are def part of the cause or at least the cause of the fluffy / smelless plants that are popping up , but then some are doing fine ,

Crazy shit going on and no idea it was this wide spread - keep the info coming but gonna go rest my eyes and toke some of the good buds that i'm wondering how long it will take me to get back to making - shit used to be super easy when i didn't know what the hell i was doing - back to basic's i suppose :banghead:

appreciate everyone's input

Fusarium alone doesn't explain everything.

I had one Tangerine Kush from seed display Mosaic like leaf patterns. I've seen a few OG's do that too randomly.

Yes, intense heat will make your buds fluffy and it can take away the smell.

the mosaic/etc whatever splotching leaves etc.....has nothing to do with fusarium is more like it. Mosaic like leaf patterns are mosaic like leaf patterns...........

Do you think the Mosaic patterns are TMV? TMV is passed through seed.

Im just saying some cuts carry dormant TMV, dormant powdery mildew and probably other viruses. Add all these together and you have an immunue
compromised plant. I think this combination is probably the reason why our plants freak out and do weird stuff from time to time.

I just harvested a mother that gave me problems, snapping branches and slow growth. I let all my plants dehydrate before I harvest them, so im not sure if this affected the stem.

I cut the stem in half, all the way to the root ball. It looks plausible that it could be fusarium. I see patches of brown. I never cut one in half like this before, but I'll peep out the other moms to see if they are all green inside.

very interesting......good work looking for this. itll be interesting to see if tests come back positive for fuserium and if others also find the same dark colored pith in their duds.

I saved a couple stalks from affected plants... they are thick and weird-looking with the horizontal branching. I will take pics soon...

I really wish people would just listen to me about the TMV thing. It is a very real problem! Over the last three almost four years I have seen almost all the issues people have posted and talked about on this thread. The virus causes so many different symptoms that look like one thing or another, but are all traced back to TMV. You can fix a lot of the symptoms but it dosnt cure the cause. If you have a plant that is resistant to it you may not even know you have it. Others that don't like it will be "dudded runted and stunted". I'm not just talking here, I have lab results and a lot of experience with it. I'm not saying everyone here has it, but I would bet that if the majority of people here would go get legit lab testing done it would be positive. It can be spread through seeds clones or even touching an infected plant. It's not that crazy to think it has spread everywhere. I see it in so many peoples pics and vids online.

im listening. do you have lab results that show a positive test for tmv. you should post the results with the identifying info blurred out as others have claimed it to be not found yet in cannabis other than a few very rare instances. skunk pharm research claimed that theyve only ever seen 1 plant shown to test positive for tmv.others say theyve never seen it. your test result would be a helpful indication that it is actually happening.

100's have been tested positive for TMV. i didnt start hearing about the positives until like '12 or so though so maybe their data is outdated. but still irrelevant to specific problem w plants and thread discussion

please share the lab results

an "official document" is way better than sharing experience (not discounting experience at all)

there have been lots of "I had stuff tested... it came back XXYYZZ" but I haven't had the satisfaction of seeing a lab doc... which is weird because when buds and oils get tested dudes throw up pics of the results on the quick. hahaha


ANYONE WITH OFFICIAL RESULTS DOCUMENTATION PLEASE POST IT UP
