Would topping help me..?

Cut the lower branches at the stem, trim all fan leaves that cover bud sites, keep an eye
on the leaves from day to day and snip what is covering up the areas that need light.
You can go one of two ways with each branch and bud site.

(after you trim the lower branches)

1). Leave the branches in tact from stem to button all the way up. You’ll end up with a long
buds that travel up the entire branch.
OR
2). Clean the button branches up to the main bud site and trim out the leaves from the center.
You’ll end up with heavy and thick buds at the top of each branch. (You see this mostly on
SCROG grows and super cropping projects).

This is basically the method I went for. This is an example of method #2
This is my current grow.
