Hey pal.
So, you say you into wk3. So, pre flower takes anywhere from 10-20 days max, normally its 15 days..
Then you have fattening, which you are just coming into now. How I can tell is the pistils are all still white and sticking up from your bud.
Your calyxes will swell within the next 2 weeks and your hairs will be developed in them, (calyxes) still have a ways to go out my friend.
Then ripening, will last 1-2wks.
6-7 wks of flowering depending. U berly half way.
She's right on track and a very nice job
Good luck
