It's good you waited to top, those are the perfect size. I agree with the previous person. I would top them and leave the two best nodes (each node has two growing tips.) So counting from the bottom node as #1, I might keep node 2/3 and top above that. Leave all the fan leaves and just remove node #1-just the two growing tips. This would end up looking like the pic where they were training 4 branches outward. Then build your plant from that base of 4 branches-you can top those again later, or just let the 4 branches continue to get longer, creating more nodes along them as they grow. Be sure to train those branches outward-don't let them grow straight up. This is where supercropping comes in, pinch and bend the branch and tie it in place. Be careful not to bend the branch so that you put any pressure on the "joint" where it connects to the stem-the joints of some plants are super weak. Do the supercropping slowly and carefully, but don't be afraid to really crush the stem (try to crush the inside and not break the skin.) Have some masking tape ready to wrap around the branch if you break it. This is how you build an even canopy without needing a scrog.
