I just want to get along with everyone. We just disagree on this issue. We probably agree on more than we disagree. It's common for people to disagree. You're still OK in my book.

Thanks..likewise. Yeah that's probably true!
Wow… this book is amazing and pretty much confirms everything I ripped into Sam the skunkman many years back on the dudding thread on icmag… everything from phytoplasmas, stem nematodes… witches broom … etc… highly recommend this book if u want to take your knowledge to the next level

The viroid can be latent and not display symptoms at a given stage of plant growth. When buying clones the only way to know for sure is to get them tested. The viroid is affecting nutrient uptake, therefore a non-infected plant can display symptoms similar to one infected by the viroid. What's more common: calcium deficiency or a calcium deficiency caused by hpLVd? I'd argue the former. If you have a group of plants that are fed the same, yet one consistently displays a visual "tell-tale" sign of hpLVd, that should raise suspicion and lead to testing. Your plant has something going on with the leaf twist and raised leaf margins. Calcium? Potassium? RH? hpLVd?

Yup same as what applesauce said, if day from first glance it looks fine,
Some strains just look completely fucked from the virus. Others look normal. It can be extremely hard to tell. And varies from plant to plant. I'd wait till it was bigger for visual confirmation and I'd definitely test everything. I wouldn't add another plant to my garden without quarantine and testing.

Emerging diseases of Cannabis sativa and sustainable management
Abstract
Cultivation of cannabis plants (Cannabis sativa L., marijuana) has taken place worldwide for centuries. In Canada, legalization of cannabis in October 2018 for the medicinal and recreational markets has spurned interest in large‐scale growing. This increased production has seen a rise in the incidence and severity of plant pathogens, causing a range of previously unreported diseases. The objective of this review is to highlight the important diseases currently affecting the cannabis and hemp industries in North America and to discuss various mitigation strategies. Progress in molecular diagnostics for pathogen identification and determining inoculum sources and methods of pathogen spread have provided useful insights. Sustainable disease management approaches include establishing clean planting stock, modifying environmental conditions to reduce pathogen development, implementing sanitation measures, and applying fungal and bacterial biological control agents. Fungicides are not currently registered for use and hence there are no published data on their efficacy. The greatest challenge remains in reducing microbial loads (colony‐forming units) on harvested inflorescences (buds). Contaminating microbes may be introduced during the cultivation and postharvest phases, or constitute resident endophytes. Failure to achieve a minimum threshold of microbes deemed to be safe for utilization of cannabis products can arise from conventional and organic cultivation methods, or following applications of beneficial biocontrol agents. The current regulatory process for approval of cannabis products presents a challenge to producers utilizing biological control agents for disease management. © 2021 The Author.

Does this plant have HpLVd? Roots look great. Plants were very healthy just a week ago. It just suddenly started to shrivel up and buds getting loose and not growing larger. Noticed on Sunday and has gotten increasingly worse day by day.

Growing from seed is the best method of preventing and eradicating this. Stop bringing diseases into your grow. Stop introducing cuts to your garden.

I wouldnt necessarily say hplvd. Might be fusarium. I'd suspect a fungal issue but you don't ever know unless you get samples tested

Is that the White Runtz cut you posted in the other thread?

Yeah, the twisted leaf curl comes and goes, and from my observation it seems to be an environmental. The reason why I believe so is because when I close the tent and the temps are around 83-87f and humidity is between 50-60 she looks perfect, but once the temps and humidity drops, it starts to crinkle up again.

no, it’s an ice cream man #5 from PinkBox

HpLVd doesn't look like that. My guess is that you have some sort of root rot going on.

Pink box sells hlpvd clones. People confirmed that with testing already

Dark heart says the virus doesn't survive long without a host. Other plant scientists are saying it can last weeks.
It would be good to have that information for reference if anyone has come across that?

Hmm, dark heart or scientists, which to believe.

Dark Heart likely knows, since they have spread the virus to tons of growers already.Hmm, dark heart or scientists, which to believe.

I'd just be Interested why they say that. Maybe their information lacks credibility despite having a team of scientists behind themHmm, dark heart or scientists, which to believe.
