A Couple Issues

Hi All !!! :thumbsup:

I have a couple issues I would like some input on.
First
I was sexing 3 plants I grew from seed. 2 NL/CS and a McCoy Hybrid.
I put them into 12/12 for about 7 days before I could see they all were female. I put 2 backinto 24/0 and one seems to not be bothered by this.
The other "PHOTO BELOW" has gone into full out bloom stage.
Will this plant return to veg.? This is a nice plant and I would love to clone it, I have no more seeds to regrow this strain. Will the 24/0 lighting make it hermie?
Next
I have a few seedlings growing of a Pez hybrid. All seem to be healthy.
One of the seedlings has a mutation where it grows 3 leaves per set instead of 2. I was reading on plant genetics somewhere and this is some hind of poly something or other mutation. It looks to me to be an advantage having more bud spots. Is anyone familiar with this? Will it affect the quality of the flowers? Photo below

Thank you all for any help on these questions.

Sorry for poor quality photos, but I think you can see what i'm trying to show.
