bene's come from the tea. they'll be ok until you can brew another tea for them. i would use the myco dust during transplant right on the roots when you pull them out of their current pot.
24 is ok, but 36 is better most likely. if you just added the BSM... i'd probably wait another 24h if it were me. and honestly, i would use the tea you have now for your veg plants since you have the kelp and alfalfa in there. the soil you're going to cook doesn't need the alfalfa or kelp in the tea. just EWC + BSM. it's fine to water in your cooking soil with the tea you have though. and make sure you moisten the soil well, but not to the point where it requires any run off.
i believe you have a small air pump and small container you're making tea in, yes? you could make a more concentrated tea, with 2tbsp of BSM in one gallon h2o, and 1 cup of EWC/Compost, and then when the tea is done add 2 gallons of RO to it, and you have 3 gal of good microbial tea.
