Post harvest root/soil question

Just finished my first harvest and was wondering what others opinions are with regards to the roots. Do these pics show rootbound? Does there appear to be anything wrong with the roots at all?
Was also wondering if the soil is ok to reuse as is. Most of the roots stayed together and there is very little in the soil. Is getting a chemical like Cannazym necessary? If so, how long before next use should I apply it to the soil? The soil was flushed twice prior to harvest and very little nutes were used in them to begin with (2 month grow). Thanks for your opinions!

Not necessarily root bound but they could use some more room for sure.

Thanks! I was thinking the same thing..as pics of rootbound roots seem to be wrapped around more intensely than these, but ya...likely could have used a bigger container. I was in a 4 gallon for a 2 month auto grow..plants were less than 2 feet tall.
