Is this the correct way to topp your plant?It will usually actually grow smaller buds, but more of them than a single cola. Looks like that someone tried to tell you about LST, low stress training, several threads about it in the forums, plenty of examples.
It's bent too far near the top, point is to get the plant horizontally. Anyway, the plant doesn't look too happy, I suggest forgetting about trying to get bigger buds and lst and just try to grow a healthy plant.
