Just harvested my first grow and was hoping for dense, fat nuggs. Made sure I had good light penetration, correct temps and fed with Sensi Bloom and bud link. 3 Weeks prior to harvest, gave them Canna PK 13/14...swapped Sensi and Bud Link for Overdrive...then flushed for 7 days before chop. As of right now, I have dense, hard nuggs from my cheese grow. Following this I ended up with 3oz per plant of dried bud x 18 plants.
My nute schedule has seemingly worked a treat...maybe it can help you get nice tight, dense nuggs, too.
