My guess on the phlox is aphids. They may be gone now, but earlier feeding can cause leaf curling. Check for sticky honeydew. Here is a reference with other possibilities:

I will add herbicide damage, which can also curl leaves.
As for the hosta, I can't see what you are describing very well. Hosta leaf edges will curl and burn if the plant gets too much sun. But also, check here:

If the hosta is near the phlox (and other plants are affected), I would suspect herbicide drift more strongly.
