question about bio grow and bloom

hi guys first time grower im using bio grow, bloom and topmax when i go to flower do i mix all the nutes together when i feed or do you use them seperatley. any help would be great thanks

the grow is mainly for the veg period of growth, then the bloom is the main nute to use during flowering and the topmax is an additive that should be used sparingly depending if your plant can take it or not without burning or overdoing a certain nute.
