!!!how to feed nutes help!!!

im on week 5 of veg just got my ff nutes for soil, I mixed the tsp into distilled 1 gal water jugs, 1 jug with bb, 1 with GB , and 1 with tiger bloom, but am I supposed to feed it with each jug or all at once?, im gonna start flower stage Monday, and im starting nutes Monday . Am I supposed to mix the correct amount of nutes all into one 1 gallon jug? im confused. Help

You can mix it all in one jug next time.I would stop giving the GB a week or two in to flower.
