Unless you're growing indoor, you don't want to give them much nitrogen at this point in the season. Having said that, Alaska is a good brand for quick nitrogen uptake.

So the fish stuff ya think then?
If you're growing outdoor, they should be flowering. They'll always need some nitrogen, but too much will decrease the flower production.
If you're growing indoor, and they're still in the vegetative phase, load them up with the stinky fish stuff.
I think they are just about to start flowering?
