NL25: Baby set on a monotone flop

[cestlavie]

Villain seems somewhat loose and passive preflop but shows some postflop aggression. Stats 30/0/3.4 after ~40 hands.

Had villain made a decent-sized raise I would've pushed. I decided to pot it after the minraise instead of pushing, planning to push any non-spade turn UI. Should I be inclined to push here anyway regardless of the small size of the pot to protect my hand?
