Need Help with TOPPING!!

I was wondering what do you guys think about topping??? Everytime i grew outdoors or inside i never topped my plants so i ended up with just 1 big cola... I was wondering if i should top these plants that im starting or will it mess up the plant?? I kind of payed good money for seeds and i dont want anything bad to happen to the growth....any recomendations would be great thanks:jointsmile:
