First outdoor grow - Sativa confusion

Ok guys, been out the game for 7 years. I used to grow indoors so I'm not a complete newbie.

First of all I have better trich devolpment on my side of my plant than the top and please remember it's outside and the sun is above at all times (sunny South Africa) before commenting.

First pic is the top kola and the 2nd pic is the side branch kola

The next issue is I've been flowering for 12/13 weeks and still have at least another 2/3 weeks. I've heard of long flowering periods for Sativa but actually not spoken to anyone who's been thru a 4/5 month flowering period.

5'6 ft plant coz I topped her.

As long as she has long white straight hairs standing up, she's not ready. I'd say at least 2 - 3 weeks minimum. How's your weather, still dry and warm/hot during the days?
