I didnt realize branch angles were also affected by it. I grow 100% outdoor and I noticed with my last run, which was all clones, several plants had wider branch angles, like the pics a few posts above, and I was having to support the fuck out of them as they got heavier.

edit: I had an MB15 from pink box in with my last run, and it was acquired around the same time frame as other people who have tested the cut and got a positive diagnosis.

They dont all display the horizontal branches but that is one of the tell-tale signs. When you observe that, cut one of the branches and then bend it. If it snaps off clean, its likely dudded. That along with those pinwheel pointy shaped leaves -hard to describe - thats why I saved that pic for illustrating (wish I could credit the pic but I cant recall what forum I found it on) They usually have light green stems and undersized fan leaves too.
When I'd observe any of those traits, I'd cull immediately. I also took cuts from the tops closest to the light. This helped a lot but nothing truly eradicates it other than letting go of infected cuts and being meticulous about cross contamination.


If you suspect your MB15 is dudded, get it out your grow asap. It sucks but you dont want it to spread throughout your garden.

That is exactly what my ICC from HM clones looked like. Exactly! I was sure it had to be pests but I scoped that plant for literally hours until I was damn near crossed eyed. And I dont mean with a handheld scope...I used my compound microscope and went over each leaf front and back and couldnt find a single bug or egg. I had no plans on keeping this cut but I didnt want to chuck it until I'd satisfied my curiosity so decided to dunk it in Kontos because I know broads can be tricky to find. Then I took clones - only two rooted out out 12 - and they grew back the same way. Dudded all TF.

I'll try to get my pics uploaded. Its very likely there's more than one pathogen (HpVLd) being spread around due to poor horticultural hygiene. Hopefully threads like this will help growers have more effective strategies for identifying pathogens and keeping healthy stock

Agreed, getting contaminated, or even potentially contaminated plants out of your garden is a must.
Whether its Powdery Mildew, or HPLVD, just let it go, there are more fish in the sea.

I still find it amusing that Darkheart Nursery had no idea about HPLVD when they sold me dudded GG#4 clones back in 2015/16.
After figuring out what was wrong with those clones, via cross referencing RIU, I informed Darkheart through an email.
Their reply was that such a pathogen/disease didn't exist and that it was just grower error.
Well, about two years after my initial inquiry stating that their GG#4 clones were indeed dudded/infected, Darkheart decided that HPLVD does in fact "exist".
Now they are the recognized industry leader on HPLVD research even though they've probably spread more HPLVD through the community than anyone else.

The denial was so strong back then its almost comical to go back and re-read those threads related to GG4 (circa 2014). So many just dug their heels in exclaiming "grower error".
I'm sure it was present long before then just not as prevalent. How could it not be in such an unregulated sector of horticulture.
But when you run through enough plants you get to a point where you just know something is off.

And yeah, DH "leading the charge" after infiltrating the growing community with this plague is dubious at best.

There is a 100+ page thread on icmag about it that got closed because people like chimera were saying it just a magnesium def, and everyone started arguing that it was more than that.

From my understanding they were just a clone nursery, then a group of scientists teamed up with them. But don't quote me. But then again maybe some of us have passed it around UNKNOWINGLY. but at least I guess they are doing something about it now

I'm not a dark heart fan by any means but duds were around long before dark heart. I remember the thread on icmag where we were trying to figure it out for years. People did link mites and either toxins or a pathogen and some people swore it was nematodes. I thought it was fusarium until recently.

Can I say another thing.. When I had hplvd my plants had taco leaves sometimes and I couldn't figure it out because rh was high and they were well watered.
My theory is that the viriod also slows water uptake as well as nutrients. So that if you have a hot humid environment, the leaves can't get enough water and they taco slightly. Just a theory.

Another thing is that rooting clones became a joke. I went from 100% of the cuts rooting to maybe 10%.

My friend treated these plants over and over again for mites. He actually started a new grow and everything was thoroughly dunked in forbid and avid more than once. I'm very certain he didn't have mites. But the same thing happened to him, he would take clones and they would grow out exactly the same way again.

Yeah, thats what set off alot of the bickering. Mag deficiencies are easy to correct yet there is always someone in the comments labeling every plant issue a Mag problem.

There's no nutrient deficiency that I've ever seen that can fuck up a plant like this can. I mean I've flowered out some really shitty plants in the past in a shitty environment too. But always ended up with something pretty good. Hplvd reminds me of leprosy but for plants.

Yeah I've been there. It's quite sad. Especially if you have cuts that are not replaceable. I lost a couple which were just in a small circle and these are lost for good now. But we never knew about this virus then.
