The point of brewing a tea is for the microbes to "take over" the base-water. A concentrated brew may just bite you in the butt by not allowing the room and oxygen they'd need to grow.
You too dress after brewing, brewing puts more of the beneficials into an already useable state. You can't foliar a top dress, but you can brew foliar and too dress the left overs, etc.
Hahahha and if you read the link shared they also don't say ship direct. Most places don't advertise drop shipping and if you've ever worked in any kind of sales you'd know it's common in alot of industry, live animals shouldn't be one.
Join any worm composting group and research for yourself or place some orders and watch them all ship from different states. And please separate the blues from reds and let us know how many of your reds you paid for aren't.... Your choice. Much better places out there- Green Greg's, Texas worm...

You can mix one shot in when starting then topdress around when start seeing flowers, can pick up your choice of liquid or dry feed, pick up tea blends, fish hudrolysate, lots of options and ways to go about feeding.
Only thing I'll add is this close to season bokashi may be the only viable for this year's use. I'd get a worm bin going now so it's ready for next year ahead of time.
You need to use brown sugar, you don't want to add extra liquid in. All the liquid will come from you sourced material if done properly. Watch the Chris Trump videos, highly informative.
Im hoping to cross with some autos one way or another. Good to know a more common name!! I knew would be a long one so already planning some garage space.
