My understanding: Eps 2,3: All clones. Not brainwashed per se, but there was a chip in their head which could control them under specific circumstances, and was used to make them turn on the Jedi in episode 3.
Between ep 3 and 4: No more clones made, as the existing clones age and die they are replaced by volunteers and conscripts.
Eps 4-6: Almost no clones left. Pretty much all volunteers and conscripts.
Between 6 and 7: Empire collapses. First Order takes over stormtroopers. Fill their ranks with stolen and indoctrinated children, I guess because they no longer have the popularity or authority for other methods. I don't think it's force control, not enough Sith to do it! But possibly some other sort of brainwashing, there was something about Finn being sent for reeducation.
