nutrients://\\ //\\// //)) flowering

i am using tomato food for flowering as it gives higher crop yields, and a little epsom salts, a little bit of chempak 20:20:20, and a foliar drip feeder for flowering plants...Might add some bone meal too.
Is it ok to be mixing small amounts of each of these nutes in a bottle to feed through the budding stage??
i have been using this mix for about 4 weeks, and one of the plants is doing fucking great! the other was a weak plant straight from the seed and it isnt liking something im giving it. I dont really care bout this plant though as a have 2 more doing nicely in veg.
But my main ???? is the above and will these nutes be cool for flowering?
thanks

from what i understand the P (phorphorus), i think it's the second number is supposed to be higher for flowering. the first number N (nitrogen) is for rapid growth. this should be low during flowering. so the 20:20:20 can't hurt, but something like chi ching, or beastie bloomz by fox farm will most likely give better results. i think bone meal helps with the PH, calcium. but i'm no expert. only growing for a year, but i hope this helps.
