Pics!!! 5 weeks seems to be too short unless they are autos
whats the Flower time for your Strain
Do you have an jewellers loupe to look at the trichomes.
Some run nutes till the end, some stop a week before harvest and flush the last week.
Pics will help people tell you if it is close to done.
It depends on how long it takes to flower your particular strain.. You need to provide more information to get accurate answers to your questions bro..
