Has it been hot?
Leaves look healthy, otherwise. Top leaves more important.
If worried about watering-- let top 1" dry before saturating pot again with some runoff. the runoff prevents buildup. Allowing it to try on top prevents microbial problems in roots. Feel weight of both states - wet and ~dry before watering. As plant grows more, you'll notice the pot gets lighter faster - a cue to increase irrigation rate or amount, whichever works best for context at time.
