General mj growing?
Advanced mj techniques?
Dunno for sure but not in here.
Anyway there isn't just one best topping method.
For example if you want to veg your plant for a short period
HST(high stress training) aka topping to 4mc or 2mc will stress your plant serioysly.
You could just bend the top down and wait for the lower tops to grow.
You can even top a plant to get 4 main branches and then top the tops again to get 16 tops.
One good method i use for myself is UB's topping to get 4 branches, and then tighing them to horizontal cross-shape wires to get a bushy plant with no main colas
