If you ask that then you don't have a magnifier to look at the trichomes and know the trichomes ratio ( The maturation level) so the only way to say if she is ready is to stick to the breeder flowering recommendation ( in your case 8 weeks so she is suposed to be ready ... suposed ) or to use the pistils method which require you to chop when at least 80% of your pistils are amber and in your case you can still wait a bit but to know how many times check a magnifier or watch your pistils 😊✌️🏼
