Fry organic feeding?

I’m in flower not sure how far along exactly but I’ve feed once when swapped could check my journal for exact date. But I use gaia green fry fertilizer and was wondering if I should wait till I see signs of wanting food or feed on a schedule? I feed 1tablespone flower half all purpose an half glacial rock dust. Ph to low 6.3-6.0 some say high I like it atm.
