should I re-pot?

Hi yesterday marked 4 weeks of veg for my 3 little babies, and before I turned my lights out I just checked the bottom of my 5 gallon buckets and my roots were coming out just a bit, is this a problem? Should I re pot them? I don't really have much more room so I went ahead and shut my lights off and will be turning them back on at noon today to start the first on cycle of 12/12. Thanks dudes!

How long have they been vegging for?

No its not a problem. Usually when this happens it needs daily watering/feeding and is almost impossible to overwater.

Man, you have some serious plants to come out the bottom of a 5 gal pot after 4 weeks. Just cut them off as they emerge, there really is no problem, or solution. Peace out

So if I cut off the roots hanging out it wont harm my plant or stunt it? Also I just flushed them around 3 days ago so they're still a little moist. Ive been doing the ehole water them when I put my fingure I the dirt and its moist up to my first knuckle or when the pots are light, should j be feeding more often? I dont want to overwater.
