HOW LONG SHOULD I FEED FF NUTRIENTS BEFORE GOING INTO FLOWER?

-FEMALE GSC

-2 1/2 MONTHS SINCE SPROUT

-52 DAYS SINCE SPROUT

-FFOF 5 GALLON FABRIC POTS

-FF NUTRIENTS

SO I RECENTLY JUST STARTED FEEDING MY PLANTS FF NUTRIENTS DUE TO MY PPM GETTING LOW ON MY RUN OFF. I HAVE ONLY FED IT FF NUTRIENTS ONCE I FED THEM 1.25 ML OF BIG BLOOM PER GALLON, 1.25 ML OF BOOMERANG PER GALLON AND SOME CALMAG. BEFORE THAT I WOULD ONLY FEED IT WATER WITH MOLLASES AND ORCA. WOULD IT BE OK TO GO STRAIGHT TO FLOWER AFTER ONLY ONE FEEDING? OR SHOULD I FOLLOW THE FF NUTRIENTS SCHEDULE?
