Does anyone know what this is? Is it harmful?
It looks a lot like spider mite webs. It doesn't usually kill the plants, but will affect your yields and possibly the taste.
Thank you. Would it make sense to cut off the one affected bud to stop the spread or is it already to late for that?
It's likely too late, but there's no need to kill off any of the plants or damage any colas.
Look into a spray meant to kill them off, and consider boosting the airflow, lowering the temp, and increasing humidity (if possible).
They don't like heat and dryness. Do not boost humidity. Make sure to apply insecticide 3 to five times. Their eggs can survive even after they die.
You really shouldn't spray a flowering plant. I wouldn't want to smoke neem.
Yeah this.
Annoying feckers.
I've only seen them on others plants, but it's pretty distinct.
Aphids are truly the worst IMO. Fuckers will move into your house and bite anything that moves (or doesn't move).
Once they start making webs, they're everywhere. They need very little to get going.
Looks like spider mites. Mix 1 part 70% isopropyl alcohol to 3 parts water in a spray bottle and spray the plant once or twice a day. Make sure you get the underside of the leaves. The alcohol is a contact killer so it will probably take a few days to get rid of them. Give the plant a quick rinse with plain water before harvest. This is the method for herbs and vegetables. I don't know if there are any differences for your particular plant.
Take pics when you chop so we can see how it affects the plants.
Those are the last pictures I have. Harvest was not all that big but that could have also been due to other reasons as I haven't seen any more webs after spraying with tobacco water for two or three days
