The stage could be early flower only because you are using natural light from a window and that's about the color of the sun this time of year more into flower. Change your light cycle into 24/7 keep them on and they will veg some more.

Not sure how much room you have to grow in, those are in dirt not Hydro so you can't just wash off the roots and move it to Hydro but you can veg it longer and then take some clones.
