Hey friend, very healthy roots. If you intend to stay in veg for a lot longer you could always repot into a larger container. I rarely have a plant that doesn't have a decent bit of root showing near the top when i use my fabric pots, sometimes I've added more medium on top otherwise i just rub the top bit back over the roots if its shifted from watering.
The plants look healthy and the roots do too...so two good positives. ✌️
