flowering question...

just started the flowering stage about 3 days ago
went out and bought some "bloom burst" plant food, which is 10(N)-52(Phosphate)-10(potash). should i use this on my plants now or should i stick with my 10-15-10 plant food for flowering?
any suggestions would be greatly appreciated!

this is my first grow and im just trying to get as much info as poosible after
already ready the FAQ
thanks

any suggestions?

yes start using 1/4 strength

1/4 stregnth of what?

1/4 of the dosage suggested on the back of the box

will it definitely help the flowering of the buds??
