I find that multiple topping makes not only for poor plant structure but also poor flowers.
I tried to find pics of your grows antimatter, but i couldn't. Can you post some pics and or data on your technique
I do it in order to keep the plants a certain height, I grow large plants indoors and I like to keep them under 6 feet for my vertical hanging bulbs. Structure wise topping does make the structure weaker as you have Y's that need support or they can snap much easyier then if the plant was left untouched. Topping for me does not give me more weight, I feel it just makes more smaller colas but more numerous, but once again it allows me to keep the plant a controlled height. I only like topping when there smaller and long before going into the flowerroom, if there to big you just get a pointless Y structure, you want it to be done in a way that you have many colas not just a single Y. I consider it a bonsai technique.
