It looks like cochineal or scale to me. The above links to info about how to treat.
It looks like you caught it early that’s REALLY good because it give you the upper hand!
If you can just remove the affected parts of the plant I would do that AND introduce lady bugs.
If this is an outdoor grow it is hard to regulate the humidity but if it’s indoors raise the humidity if possible because they survive in dry areas. I don’t know anything about growing indoor so I couldn’t advise on the highest safest humidity for that.
From what I read about cochineal and scale they don’t respond well to many organic sprays because they have a hard protective shell over their bodies. If it’s late in flower you probably don’t want to drench in anything.
If it is indoors maybe you could do some sort of chemical bomb????
If you can pluck them off and/or remove as many affected areas then put some lady bugs in. I would put in A LOT of lady bugs, even indoors...
Or
Spray pyrethrins (Monterey Take down spray or something like that) would knock them out and if you make sure that the plant gets good airflow and don’t drench the buds you should be ok. I really mean don’t drench the buds! Light mist and let the wind/fan carry the mist to the plant. The pyrethrins will kill the ladybugs so you probably don’t need to add the ladybugs if you decide to spray or bomb
