Growing in soil?
Mycorrhizae and Peruvian Seabird (10-10-2) + Indonesian bat guano (high phosphorous), kelp meal or liquid seaweed (Maxicrop), molasses for additional potash and trace. But, with only a couple weeks left until harvest it's too late for much of that. Those buds should continue to bulk up anyhow, they may have stopped growing temporarily (this happens). As far as bottled liquid nutrients go Earth Juice Catalyst is a popular additive that can pretty much be used up until harvest.
