:yeahthat: The differences in the number of fronds on a leaf, be it a fan leaf, sugar leaf, or early veg leaves, means very little. As yu grow yu will see a lot of variances in leaves even on the same plant, this is not unusual. If yu have a definite trend across a plant of leaves doing something unusual then that could be a symptom of an issue, and I would recommend posting a pic of it here. But if iti is not a plantwide trend I wouldn't be concerned.
