How long until I should give my girls the chop?

Hi,
I’m a noobie so I would be greatful for any help..

my fastbuds original cheese autoflowers.
How long would you say until I should give them the chop?

thanks

I would wait for all the hairs to change color and die back also check the tricombs they should be at least 10% amber as well. She doesn't look ready so don't murder her yet. put the knife down!

Minimum when the white hairs become brown or red and go inside the plant(or plant grows soo big it looks like thaz) you have lots of weeks to go

They’re right. Weeks.
