They look good to me...just curious why you are moving indoors? You looking to flower? I dont know much at all but I have been told to check, check and triple check for pests when going from outdoor to indoor.
In my limited experience, I have been able to induce flowering after the first four weeks of good veg growth...then I flowered for 6-8weeks and had some decent harvests. Nothing professional but the folks I gave my stuff away to certainly had no complaints. Thats my current schedule (when everything is going right with nutes and all... and I am growing from clones).
They will start to flower when you decide to force them to. When you change their light cycle to 12 hrs on and 12 off they will begin to flower a week or 2 after. Just remember the dark period MUST BE COMPLETELY DARK!!! NO LIGHT LEAKS!!! Edit: Also are there more than one plant in each pot?!?!?!?!?!?!?!?!?!
YES! There isn't enough room in that pot for one fully grown plant much less multiple plants! Not to mention the fact that the roots will become intertwined, making transplant nearly impossible. You need to get them out ASAP, and even then I cant promise you they aren't already tangled. Edit : You need 1 gallon of soil for each foot of plant or you risk them becoming root bound.
