Transition to flower soon ...what nuets should I be adding?

Hey everyone . I have 6 Blue Dream’s growing outside here in Michigan in phat sacks using Great Lakes organic Water only super soil and coast of Maine lobster compost top dressing .
Getting ready for transition to flower and wondering what everyone is using ? First time grower here, I’m not excepting a huge yield but at least hoping for some decent dense frosty budz . I was trying to get ahold of some Root Organics terp tea but hard to find anything in stock with Covid .
Thanks in advance for any advise !
