Flowered too early

Allright so i have these 2 plants that were female in veg for about 5-6 weeks and they both started getting alternating nodes and showing preflowers so i started them on 12/12 which was like a week ago. but now im thinkin it may have been too early for 12/12 because they're not that big and im worried i wont get a good yield. i'll try to get some pics up soon but i just need to find my cord. so yeah, what do you guys think?

Plants usually get 2-3x bigger during flowering. They also usually develop a lot more side branches and nodes and whatnot. It's only been a week, give it time. It takes a few weeks for the plant to get into flowering mode sometimes. Anyhow, how tall is the plant?

my plant was 6in tall when i started 12/12. i think you'll be good.

I had a plant also flower at 6 inches. Ended up being 16 inches at harvest. So almost tripled in size.

the one is about a foot, and the other is about 1.5 feet. I LST'd them. so how long into flowering will it keep growing more nodes?
and how much did you guys harvest per plant?
