If a plant is supposed to flower for around 60 days would it be better or worse to let it keep growing just a little while longer, like maybe a week or two, just to be on the safe side?
the best way to check doneness is with a jewlers loop. in my opinion you should get one so you can harvest at the peak of potency. if you really cant get a loop in my opinion its always better to go longer then to chop too soon. But only wait like a week tops. If you wait too long potency can degrade
It can take longer to flower a strain outdoors than it would with the same strain indoors. Most listed flowering times are referring to indoors. So chances are you will need to give them a little longer anyway. Just wait till almost all the pistils change color to get the most weight and a good high.
