Sorry for your loss , I have readen somewhere that an infected plant can give negative in a test and then positive two weeks later. I have bookmarked your post, that answer from Alfonso is gold, you can see the importance of detection and it also provides the tools to get rid of it.
I have detected some negationists here in OG, speaking that it’s only variegation, but it’s spreading fast with clones and cuttings sent and even seeds, I may panic just seeing possible cases but just the idea of losing the entire crop entitles me to do at least a friendly warning …
Thanks for sharing that precious info, hope testing is more easier and available, it will help to contain the spreading …
In 2019, beet curly top virus (BCTV) was first reported in hemp in Colorado. Hence, we were motivated to understand the diversity and prevalence of BCTV strains infecting hemp in Colorado. We detected BCTV at high incidence rate (81%) in leaf samples from 12 counties.
But most importantly:
Virome analysis revealed the presence of both virus and viroid sequences that had high nucleotide sequence identity with GenBank accessions for cannabis cryptic virus, cannabis sativa mitovirus, citrus yellow vein associated virus, opuntia-like virus and hop latent viroid. In contrast, tobacco streak virus sequences were highly variable compared to sequences in GenBank suggesting a possible new genotype of this virus.
In an RNA-seq experiment conducted on a diseased Colombian Cannabis sativa hemp plant, we identified a linear single-stranded RNA (ssRNA) genome belonging to Tobacco Necrosis Virus A (TNVA), a common cause of necrotic lesions in plants such as tobacco and tulipa. The affected Cannabis sativa hemp plant exhibited severe symptoms, including alterations in pigmentation, leaf morphology such as chlorosis, necrotic tissue formation, and surface wear on the leaves.
Not everyone can afford to do genetic sequencing on possible infected plants, so until science can catch up… I would ask myself if it’s really worth running the risks of keeping said plant. It could pop negative for TMV or HLVD, yet have LCV. We don’t know yet if these viruses transmit through seed or not too.
I brought this all up to the geneticist who I suspected of providing the host plant and he thankfully confirmed that he hadn’t had a viroid in any of his cultivation spaces. He then released a bro-science collectable card after closing my ticket, which I took personally.
Any insect thats sucking on your plants and walking through the juice dribble and walking it on thier feet all over your plants is a potential vector of viruses Aphids Thrips Ect I meant think about it thier like little dirty syringes too with thier mouth probiscus they aint wiping thier mouth in between meals
Those are a bit established for it to be the same cause as mine, it seems. Hard to get a good view of your white dots, but I’d do ipm in the mean time and monitor closely.
Here are my emperor haze ix that are showing something similar but I’ll keep you informed on if/when they grow out of it. All others have on my end. Wishing you luck!
You should separate and quarantine the ones showing these symptoms and watch their progression, if it’s finally a virus it could contaminate the rest of the crop …
Variegation normally it’s seen on half of the blade or leaf:
I’m sorry for stressing you out , but they look both infected, if possible you should test them because my diagnostic is only based on suspicions, you should look for more certainity before taking further steps …
I noticed when I feed the plant more food this anomoly goes away somewhat. it seems like the plants are really strain dependent on the amount of food you need to give it. Just my 2 pennys of bro science.
