Able to re-veg?

Hello all.

After 5 days of 11/13 I've decided to revert my Dinafem White Widow to 18/6.
It's about 9 inches tall now and has responded to the schedule phenomenally quick(?).
I have another Dinafem Original Amnesia, started her out 11/13.

Is it ok for me to re-veg them? I plan for them to be at least a foot tall before flower. Medium is a mixture of Horticultural grade soil, Vermiculite Moss and Organic Composted Chicken Manure all mixed into one.

Using 400w HPS.

Thanks in advance.

EDIT: Forgot to mention it hasn't shown any signs of flowering at all. Just increase in height.
EDIT(2): Forgot to mention 4 inch 3 weeks from germination. It wasn't growing tall, it was growing thick. Indica phenotype White Widow?
EDIT(3): If I went along with flowering, how much would the yield be? I know Original Amnesia ain't going to be yielding much. Actually, I was gunning for 4 oz from two plants but that seems doubtful. What do you guys think?
EDIT(4): No alternating nodes.

my guess is revegging after just turned to flower is a bad idea. It will probably take 1-2 weeks to recover into more vegging. I would just let it roll and reveg it after you harvest it.

It will slow your growth for a couple of weeks but then you will be back to full tilt boogie veg after that.

Thanks guys. I have decided to continue flowering it. It is at 9.5 inches now. I have two more Original Amnesia Seeds so I'll put them down at 18/6 together with Think Different Auto Flowering under my new LEDs when this grow is complete.

Just fyi revegging is always possible.
