Oh yeah, definitely. Stop feeding them nitrogen about 2 weeks before harvest and then stop all nutes all together about 7-10 days before harvest. Just use ph'd water and maybe a flushing product like FloraKleen. (i just use water).

Flushing helps improve the taste and helps speed the drying and curing process. After that you should have some primo bud that smells, tastes, and burns great.
