Roxivusanswered grow question 5 years ago Hey man fairly experienced grower here, my first thought is not enough light, your plants are quite tall for only being on the fourth node. My guess is that there wasn't enough light to have the leaf push out all 5 fingers, or it could just be the seed genetics. I've had leaves come out with 7 blades on the third node, and even as high as 11 when in full flower as long as shes getting everything she needs.
Topping her now should stop more lateral growth for a bit, but generally I like to follow The nebula manifold technique, topping from the 6th node to the third and clearing lower growth, this allows the plant to be more robust in its current growth and lets me clone the cutting I took. You ever have any questions feel free to pop over to my log and drop a comment.
