Hey Growmie,
Looking at the picture of the plant, I would definitely say that defoliation is in order this plant is pretty bushy and could use some light penetration to the bottom to help those buds grow also. Just remember when you do it, don't go all crazy with it just remove the leaves that are blocking flower sites. Hopefully, this was helpful, and remember ..."
