If that made any sense I've been smoking some pink grapefruit. Depends how many colas you're trying to achieve to how many fan leaves you might need to remove. Yours looks pretty busy so may need a few more taking. Have you left all the nodes off the 4 main branches grow up or removed some? Some people just keep a couple of the ones growing out the sides off the 4 main branches. Some keep them all. Some keep the ones coming out the top too but it's best to just get rid of everything growing out the underneath of those branches.
