Plant is in middle of flowering?

I bought a clone about 6 weeks ago and it had the little hairs since I bought it and I've been growing it outside and it actually has a 7 week flower period so I don't know how close it is to being done but it does have flowers now and I was wondering if I could simply pluck a nug off or would it not be ready for whatever reado

3 to 4 more weeks - Just a guess.
Helps to know the strain so info can be used - Not knowing when it went into flower makes it harder to know when to harvest.

Get a powerful enough magnifer to look at the trichomes. Read up on when to harvest using technic of observing trichomes for maturity. Enjoy the smoke!

I'd say 6 weeks at least
