Female PreFlowers?

Its been a rough 73 days since they hit the dirt.
Experienced nute-burn, drought, pests and stress.
However with 24/0 light and a lot of patience they've sort-of recovered.
I think I may finally be able to decide whether or not these ladies are really ladies...
What do you think of them? My cuts weren't so close and clean when I topped in a rush.

ladiessssssssssssssssssss

Nice pics of Female parts just like she said

nice pubes

So does this mean they've matured enough to begin the flowering stage?
The shortest is 18 inches and tallest is 24. They are topped and shouldn't grow too much taller..

I also took 4 clones put in rockwool cubes.
Also attempted to root the top of a plant whose lower half deceased, but I don't expect a very positive outcome.

Still happy to be blessed with 5 females and 2 healthy unknowns.
I learned that pistils can sprout up in literally 2 days as they did on my plants.
How long does it take for balls to grow/develop and then open up?

You can flower when ever you switch the lights to 12/12 once a seedling is past its 4th or 5th node no problem.

Hey thanks I will start to flower for maybe 3 weeks or so, but then they've gotta go outside.
The lighting is probably 18 here though, so i figure they'll flip back to veg then start flowering come the fall?

Or should i not start to flower, and just continue to veg them outside. Which is better for the plant?
