How to tell if root bound?

So I'm a newbie on my first indoor/outdoor grow in soil, 1 foot tall very bushy plant in 3 gallon pot (lots of LST and she goes outside during the day, gets tons of sun). 3 weeks into flowering, LOADS of small buds with pistols starting to brown already, maybe 30%. bottom leaves turning yellow and biggest change= growth has stopped. no changes in last few days. I'm thinking that I'm root bound. pH is 6.5. maybe a little N deficiency causing the stunting but want to know how to check roots.

Question: Is there a clever trick for determining if the roots are bound up near the mid/bottom without risking the stress of actually pulling it out? I don't see them running out of the bottom holes. but I just feel like that's the problem. when I water her it runs out much more quickly than it used to.
