I have noticed some buds lower in the grow canopy, going rotten, outdoor!
I also have scale pests growing on the stems, think this might be helping the cause.
I used my usb microscope to have a closer look & got a shock at what I saw, see youtube
Crazy stuff
I would contact Arbico Organics and discuss and provide them a link to the video etc and I’m pretty sure someone there will have some ideas.
I wouldn’t delay reaching out to them cause that sht is a killer
Plenty of good bud up top but have around a kilo of premature bud (popcorn) with rot but not mold, thinking of making solvent based oil, may separate the rot from the trichomes
I’m with @MrPeat on this one. Pull them incase they spread further and do the full deep clean routine. I hate pesticides though so not sure other than pull them and start again in a fresh area . Best of luck on this one
