Help setting up a good feeding schedule!?

K so im 3 weeks into flowering, and ill have yet to set up a good feeding schedule! so i def need some help finishing strong with these, and maybe get an idea of how to go through my next? I pretty much just need to know wheather or not i should be feeding my nutes everyday or mix it up and do them every other or every third? I Use the humboldt 3 part grow,micro,bloom still using in own watering container, Also using Humboldt Ginormous, Deuce Deuce, both also in seperate containers, and for the last couple weeks i have Humboldt Big up as well as Humboldt Gravity. i also have one just plain water. To me seems like way to many watering cans, but not sure if i can Mix any of them together or woul ppm be to high,many questions but ill leave it at that. Any help,advice, ruff feeding schedule ideas? anything appreciated... Thanks

just folow the drections on the bottle you can mix them all but i would not go over 2.0 ec untill you know how your plants will take the feeding on my plants i go to 2.5 ec or 1750 ppm and flush for 3 weeks and feed once a week at a time.
