Are you able to get a clear full picture of a bud, and a clearer picture of the trichromes. That honestly would be the best way to help.
Are they autoflower plants?
That pic was three weeks ago
Welcome to the forum, I don’t think they are done yet, still a bunch of white hairs on the bud, wanna watch for almost all of them to turn an orangeish red and curl back into the bud then you want to check your trichromes for cloudy to around 30% amber color.
Will need a more recent picture to get a clearer idea of where your plant is at.
