Overfeeding or Overwatering?

Young plants can often start with funny looking leaves while they get their roots going and normally grow fine after the third or fourth set of leaves, so no real concern at this stage. I have also seen plants with strange leaves their entire lives that then bloom and flower normally. I would however ease back on the water, a plant that size and age does not require watering every day, only every 2-3 days depending on temps. Wait until the top three quarters of an inch/15mm has dried out a bit before giving more water. An over wet substrate can potentially "drown" a plant by limiting the availability of oxygen to the roots and has a similar effect on young plants as yours is showing. So, a bit less water and given time, the leaves will grow as normal as you expect them to be. Also, remember, there is no plant that will have 100% perfect leaves, 100% of the time.
