Is this a HLVd infection?

Many fastbuds seeds come infected with hlvd.

yeah so these answers are wild. hops latent is a HUGE problem in cannabis, it is already endemic. think covid or the flu. it is here to stay. it also impacts flower quality and is transmissible. you will never be able to make this call. this is a job for a lab test. this is why we never buy from walmart style seed brokers and always go direct to a trusted vendor with lab testing, because you cant confirm visually. any seed pack or clone or tissue culture you've bought in the past ~5 years should have mentioned their testing procedures for this exact circumstance

Bom dia, analisando o seu diário verifiquei que tem a temperatura e humidade um pouco altas, se aumentar a circulação do ar deve conseguir baixar esses valores que estão a provocar stress na planta.

Overall she looks healthy green, I wouldn’t be to concerned cause there are always little nutches and mostly weed has her own revival techniques. Stopp touching to often, have a good temp/rH ratio and correct EC/pH for your hydros. I would stir up a mist solution with grow veggie medium and spray it twice a day before lights turn on/off. Good luck 🍀

Unless you have been to a field of hops and undertaken pruning, grafting or transplanting hops recently, it is almost impossible to introduce HLV to your home set up. Leaf curling is not really a symptom either. The leaf curling is more than likely to be caused by too much heat or a lack of air circulation.

Breathe easy—the leaf edge curling and wrinkling ("canoeing" or tucking margins) you're seeing in the photos is unlikely to be Hop Latent Viroid (HLVd). While HLVd can cause leaf chlorosis, brittle stems, and stunting, the distinct puckering between the veins and slight leaf margin tucking typically points toward environmental or nutritional stress rather than a pathogen. Common Culprits for Leaf Edge Curling Environmental Stress / VPD Imbalance: Rapid fluctuations in temperature or relative humidity—or a vapor pressure deficit (VPD) that is pushed too high—frequently cause leaves to cup or wrinkle as the plant struggles to regulate transpiration. Root Zone / Hydroponic Stress: Since this looks like a hydro or DWC setup, minor water temperature fluctuations, temporary dissolved oxygen drops, or slight root tip stress can manifest as weird leaf crinkling. Light Intensity / Heat Stress: If the canopy is getting blasted by intense LED lighting without enough airflow or adequate transpiration, upper leaves will often react by canoe-curling their edges upward or downward to reduce surface area exposure. Nutrient Imbalances: Minor excesses or lockout of nitrogen, calcium, or magnesium can distort new cell growth, causing the leaf blades to take on a crinkled, uneven texture. Next Steps Check your current VPD, room temperatures, and leaf surface temperatures to ensure they're dialed in for week 6. * Inspect your root zone for any signs of discoloration or pythium just to rule out root health issues. If you still have lingering doubts and want 100% peace of mind, you can snip a small leaf sample and send it off for a quick PCR test via labs like Tumi Genomics or Botanacare, but based on visual cues alone, environmental or feeding stress is the much more probable suspect.
