Farlows are a loricariid, and many loricariids (such as Ancistrus) are well known for destroying certain plants. The usual case is with sword plants, as the leaves of sword plants are both large and stiff enough to hold up a pleco as it gnaws on the surface. Plants with small or very soft, delicate leaves (i.e. Nymphaea) can't hold up the fish, so if it tries to perch on them, the leaf just dumps the fish off. So, ironically, plants that are usually known for their sturdiness in the face of assault are the ones most likely to be attacked by rasping fish.
That said, I've also got two Rineoricaria parva (whiptail cats) and they can't be bothered with the Amazon sword in their tank, so it's not a universal thing among the Loricariidae.
Nonetheless, there's a very good chance your farlow is the one behind your plant troubles, especially since it's the broad leaved plants that are showing the damage. However, that doesn't necessarily mean you need to get rid of the fish, you might just switch those plants out for ones less susceptible to attack instead.
