Roots showing from the bottom

The roots on the bottom of my pots are showing. I want to keep vegging for @ least another 5 days. Would this be a bad choice?

I am new to this but, re-pot maybe? depends on how old it is, and if it has actually formed a root structure, or if it just happened to make it out of the bottom of the pot.

The height in my growspace is only 6 feet tall. They're almost 2 feet already. I want to wait till they get 2 feet then bud.

How big are the pots? pictures (of the roots/pots/plants would help. There should be no problem with re-poting them, waiting a week or two, then putting them into flower. But again, if it just happened to make it's way out of the pot, and is not making a huge ball of roots and choking it's self. Then you should be fine. BUT, re-poting to be safe wouldn't hurt the plant.

Take my advice with an extremely small grain of salt. someone correct me if I am wrong.
