Does every1 know toping and F.I.M.ing are differant.
In fimming you take off half of the growing tip.
I have done this several times and 1 of a few things happen either it tops the plant as normal. It acts like topping but the top bit grows back so you have a bushy plant with a main cola, or several grow back at the top so you get a bushy multi cola plant. Then you can do a bit of lst and make it what ever you want.
