Ah, that definitely looks like scale insects. Because of their tough, protective shells, standard sprays usually won't do much good here. If the infestation hasn't completely gotten out of hand yet, you can tackle them manually. Just dip a cotton swab in 70% rubbing alcohol and dab it right onto the individual bugs to kill them on contact. It is tedious, but it avoids using heavy chemical fungicides, which you definitely want to keep far away from your plants during the flowering stage. You might think a higher percentage like 90% or 99% alcohol would work better, but it actually evaporates too fast to kill the pests effectively. Plus, high-percentage alcohol acts as a really harsh solvent. It can instantly dissolve, strip, or burn your plant's delicate resin glands and trichomes. The 70% mix is much gentler, giving you time to clear out the bugs without destroying the plant's surface. Nobody likes having to treat their plants during flower, but this is definitely the safest path forward.
