Advice please, roots out bottom of pot

I obtained recently two clones cut off a Master Kush plant and a Purple Haze. They are four days in the soil and are around 5 inches tall. I have seen on the MK a peeping root out the bottom and the Haze has a very noticable root sticking out as much as an inch. I am afraid that the roots simply shot to the bottom instead of filling out the pot. It is a small pot, maybe 6 or 7 inches tall. What should I do?

Both plants look healthy. The Haze has some bigass leaves that are a little hanging but i'm sure that's just due to weight.

Thanks in advance!

Turn 'em over and yank the pots off, take a proper look at what's going on around the sides. If you see a "few" roots -no problem. If you see what looks like a ball of white yarn, it's definately time to transplant.
