Ohhh okay. Is it because I didnt have a large enough node to cut for "topping" so I finmed it by cutting off only the top growth?
Yes, you didn't have enough nodes (4 minimum/6 way better)
You want a vigorous, healthy plant before you top, so it can grow past your cut without slowing down
Personally, I don't bother topping anymore, I just let the plant go and count on one large cola instead or 2 or 4 smaller ones, because that's what you will get with topping
If you know that height is an issue, then I might consider topping, but I don't bother, I just LST if my plant starts to run into the lights.

I grow a lot of Haze, which I would NEVER top, I just bend them over.
These plants are mostly Hazes (3 week bloom), and what I will do is tie them down once they reach the lights, because they will be around 5/6' tall.
If I topped they would be 1/2 the height, with less bud sites, smaller colas (I get at least 1/1.5 per cola).
I run my shit (12 plants) under 1800 watts HPS in a 5x5 area, and I get great results, but if your in a tent with 1 fixture, I definitely would advise against topping.
I just like big plants, (like my women), and topping hinders that.
Next grow try not topping, and you'll see what I mean.
Good luck my friend
