First grow flowering stage just 2 weeks left

Hi Im a first timer and Ive a few questions to ask any help would be great thanks.
I have 3 different types on the go
1 Big Bud x northern Lights
2 Yumolt 47
3Strawberry Blue
I vegged them for 14 weeks under flourescent lights.I then flowered under 600w hps . I have about 2 weeks until harvest .There is bud showing but not a lot of it .
Will bud grow at a faster rate in the last 2 weeks of flowering or have I gone wrong?
My strawberry blues are giving off a stale grease scent is that going to effect the taste or does it have to ripen?
My bb x nl smells nice and has the most bud on it but not even an ounce Id say.They are over 1 meter tall.
Last of all before I flowered them I read somewhere that they are ament to grow twice there hight .Mine didnt they grow a small bit but not tat much.
If you have any comments or any help I would love to hear them thanks

You probably did all your stretching with the long veg time, I usually veg for 5 weeks

If your girls don't have a lot of bud showing, how do you know it's got 2 weeks? Usually with those hybrids, it'll be 9-11 weeks from showing the first flowers. Wouldn't worry much about the smell/taste since the flowers aren't ripe yet.

Thank you for replying on the seed packets it says bb x nl 55 days flower
yumbolt 8 weeks
and strawberry blue 9 weeks
thats where i got flowering time from am I right in going by that
