Reveg or remain in flower?

So I have a lady that's getting pretty big. She's a first run so not super bushy which is okay as I intend to reveg her my question is should I reveg her now (3w into flower) or after harvest in early September?
My goal is to yield a pound.

♦ germinated from seed (not a clone)
♦ vegged 12w under a 1000w mh bulb,flowered under a 1000w hps
♦ AN Micro,Grow,Bloom,Big Bud,Bud Factor X,Bud Ignitor,Bud Candy,Mykos and Azos
♦ 18/6 veg,12/12 flower times
♦10x8x4 tent
♦LST and supercrop techniques used. Topped at 4th node.
♦ Black Gold,FF Happy Frog,FF Ocean Forest and Ancient Earth soil mixture used.
♦30 gallon smartpot

I believe her to be healthy enough to reveg despite an issue with fungus gnats that lasted a few weeks.
My aim is 1lb of this strain so if I will likely yield that as is I would keep her in flower. If 1 lb seems zealous for her size and conditions I'd like to know so that I can reveg her and get my desired yield.

Will she yield a pound as is?

 

Knock as much of the dirt off of the root mass as possible and re-pot before flipping back? or will a good flush do it?

 

Was looking thru your grow journal and got a lady boner... what strain is this magnificent creature?

 

Do you have seeds from her? I would love the opportunity to run her...hell I'd mate with her...and smoke our babies. xxooxox

 

They DO bring back memories don't they? I had a BEAUTIFUL Lemon Kush plant that I lost the last of the clones and mama to a massive whitefly infestation. I still get teary when I look at her pics. You grew a beauty.
