Leaves Curling Up

I wouldn't worry about the curly leaves. Usually from explosive growth and the cells in the leaves kinda build up and Bunch the leaves up. They balance out and straighten up once they grow and get bigger. As for the 3 leaves. Just like the 1st and 2nd leaf to appear are a single blade And 3 bladed leaf. Same goes for the corresponding nodes. The nodes to grow off the 1st and 2nd leaf with only have 3 leaves at first. If you top the 1st and 2nd node as soon as possible. The nodes that grow will also have 3 blades. But the 3rd leaf of the plant will be a 5 bladed leaf. So will the 3rd node growing. The first leaf on the 3rd node will be a 5 blade. Its all about how the plant naturally grows. Once the nodes grow out enough they'll start growing 5 and 7 bladed leaves. Also nothing to worry about. An easy way to avoid this is to understand how the plant grows like I explained and top accordingly.
