Stonerdanswered grow question 4 years ago The first few leaves sometimes have irregular growths that will fix themselves as the plant matures so this is nothing to be worried about.
Also at this young seedling stage leaves only grow 1 leaflet, once the 2nd or even 3rd nodes develop then leaves will slowly increase its' leaflets from 1 to 3 to 5 and so on (most leaves have 5-7 leaflets, more may indicate a mutation while less indicates re-veg stress)
Keep doing what you're doing and give her some time, she will probably start growing normally in a few days.
Hope this helps! Good luck and happy growing :)
