This one works for me, however it never resets like this because it casts the spells without acquiring a target
/stopcasting
/castsequence [@vuhdo] reset=target rejuvenation, lifebloom, lifebloom, lifebloom, regrowth, nourish, nourish, nourish, nourish, nourish

To switch targets try
/stopcasting
/target vuhdo
/castsequence reset=target spell1, spell2 , spell3
