how long to haverest

Hello, I am a totaly beginer and i wanted to ask how long will this rqs ak auto strain take to haverest ? its now 5 week in flowering. Could I may already take some off next weekend. I would like to smoke it with my friends here are some pics :

Nowhere near ready. If you chop some for next weekend you will just be wasting your time and yield. A 1 gram bud now might be a 5 gram bud when ready to harvest. Not to mention your friends will just think you grow shit weed.

Ok thanks for help, I will better just buys some weed and wait.

Strange to see a plant in flower at this time of year outside. You must be close t the equator. The big sativa has many weeks to go. Its a nice xmas tree and if you leave it you should get 8 oz.
