I just got rid of a small aphid problem.
If you're inside, I'd turn off fans and air movement devices at the beginning of your light cycle. Dim your flowering light(s) or temporarily rig up a fluoro good enough to see what you're doing, but dim enough not to burn your plants.
Then spray every plant down with a habanero spray. Make sure you get under your leaves, and hit the entire plant, stems and stakes too. Wear a dust mask and don't lick your fingers or finger your dick. Let your plants drip dry for a couple hours before you turn your regular light and fans etc back on. Don't get any spray on a hot bulb, they don't like that. Clean the walls and floor, grow containers too. Consider changing outdoor clothes before entering your indoor garden. Bugs love to hitch hike into your garden, don't help them.
Repeat this every other day or even every day if you can.
This is to knock the infestation down. If your buds are past three weeks, you're close to the time spraying buds could be problematic, so while solving your aphid problem, you could be creating a pm or mold problem if you spray just before lights out or sundown. If you can get ahold of some green cleaner ( A pesticide) real quick you might consider using that on alternate days with the pepper spray. Green cleaner has alcohol in it, alcohol ain't good for trichomes.
I'd order lady bugs, today, and stop spraying after you've released them into your garden. Lady bugs like a little water, but they don't like bug spray.
Be thankful it's "only aphids" and not spider mites.
Only some of the hairs are even starting to turn brown, so I imagine I am still 2 weeks away from being able to cut em down.
