Title says it all roots over grow the pot and are sticking out,should worry about it ?
The plants look pretty healthy.
They are white widow from seed at 2 week of veg .
Don't worry about it. Smart pots will "air prune" the roots. Those are outside the pot because they are on the bottom and protected from the air and light. Nice looking plants man.
That' exactly what smart/fabric pots are supposed to do. Allow roots to grow "thru" material. The tops just die off after a day or so. Perfectly normal
