m0useanswered grow question a year ago I don't think they are aphids, they lack some of the features I identify aphids as, they do look to be a pest and inadvertently getting stuck in the trichomes and dying on you. I normally see aphids with the black spikes coming out of their butt. google brown aphid and look at some closeups and compare it to your bugs. I think you'll find they are different. It kinda looks like a soil mite given its crazy small size.
Any time I have had aphids on my plants they do not go for the flowers or highly trichomed areas, they aim for the leaves and the stems of the leaves sometimes the trunk of the plant depending on its age mostly under side of the leaves where the veins are.
I think this is something from your medium and they are just exploring and getting stuck.
Use a hose and spray most of em off outside, then spray down the plant with regular dish soap and water, let it sit for 10 min and rinse off well.
then treat the medium with something call BT or some nematodes. the BT is a bacteria that kills a lot of larva in a bugs life cycle and nematodes are microscopic parasitic worms that eat/kill them in a few different life stages. Can also put a thick later of sand on top to help prevent then from crawling out. Diatomaceous earth also known as (DE) can be mixed into the sand to make it extra effective, its like walking on broken glass in bare feet for them, cuts em open and then they bleed out. however this stuff does not work when its wet, only good if its dry. It can be a respiratory irritant as well so don't go dusting the entire plant and then smoking it.
one last step is to get some double sided tape or sticky traps and wrap the trunk of the plant so if anything is trying to crawl up the base of it they are stuck and trapped immediately and not in the buds.
Good Luck!
