I have read that it's common for roots to poke out of the fabric pots, and that they get air pruned which is healthier for them that being stuck with nowhere to go.
"Air pruning happens naturally when roots are exposed to air in the absence of high humidity. The roots are effectively “burned” off, causing the plant to constantly produce new and healthy branching roots. If roots are not exposed to air, they continue to grow around the container in a constricted pattern."
That's what the almighty Google said haha
