Typically at this point in bloom decrease the nitrogen, increase the phosphorus (increases bud sites) and potassium (increases density). Some thing like PK 13/14 works well. Giving the buds plenty of light (intensity) with an increase in the red spectrum will also help with bud density. Also keeping temperatures around 75-76 in the last few weeks of bloom with lower humidity 35-40% is best to preserve terpenes and THC. There are also some products which claim to enhance resin and terpenes but you will get a variety of opinions that they really make a difference. Good genetics = Great bud. Indica strains tend to have denser buds than sativa. Skunk has both. Hope this helps
