Can you put a lower level domain spell in a higher level domain spell slot?
Yes.
Also, if you have a metamagic feat that increases the spell level by +X, you may also place that in the appropriate level spell slot.
HERE is Sean K Reynolds on the matter:
You can, you just have to use your higher-level domain slots (as you mentioned). Likewise, if you don't like your 4th-level domain spell choices, you could prepare a lower-level domain spell in your 4th-level domain spell slot.
Thanks for the info!
