Tree collard cuttings blooming

Hey all, I got these cuttings in the mail maybe a month ago, and all four seem to be doing great. Almost too great, I'm worried. they are starting to put up little flower heads! I've never grown this stuff, and never expected little cuttings to be trying to bloom, especially not so soon after being put in soil. I didn't pull any of the out, but I can't imagine their roots are THAT established yet. Are they entering some sort of last gasp of life, trying to go to seed before they die, or what? I'm hoping it's just a hold-over from the parent plant's yearly cycle and they'll just carry on, but thought I'd ask you all. Thoughts?

A friend gave me some Longevity and Okinawan spinach.  The Longevity spinach was trimmed and I put the trimmings in pots and they all are growing.  Looks like spinach breakfast lunch and dinner.

I also got some World's Best Mulberry and some Goumi cuttings maybe 3 to 4 weeks ago.  They are all taking off and it looks like flowers already.  

I have a growroom (9x24ft) instead of a greenhouse so it is insulated and has lots of power outlets.  I built a humidity tent, with pond fogger and humidistat and plant heat pads and it seems to be the environment they love. I am spraying them 2x a day with vitamin B water.

Problem I have is, when do I take them out of this environment and repot them so they can harden to the real world?  If I have to wait to April they will have out grown the humidity tent.

Brandon,  I see you are in Austin.
The weather there seems to be in the sixties.
Looks like your last frost date is the 15th.
Are your plants inside right now?
If so,  the indoor  warmth might have pushed them to flower.
Maybe wait until the 15th  and plant them out.
If they are already outside, maybe  let them be.
Hopefully they are reacting to the nice weather.

They've been outside in pots, though I brought them in for a day and a half because it dipped down to around 30 one night. It was 83 the day before, and has often been in the 60s and 70s all "winter" here. I'm new to this climate, as much as I'm new to tree collards, so I guess this'll just be a learning adventure for me, as with the rest of it.
