Is this normal? My plants are growing roots off of the leaves and it
appears they are trying to get to the substrate. Is that okay or is
there a problem?


It's normal, but it could be a sign that conditions are less than ideal.
Cabomba for instance will drop roots all over the place if it isn't being
pruned enough and the bottom portions of the plant isn't receiving enough
light.

If your plants look the way you want otherwise, don't worry about it. Any
growth is good growth.
