Fox farms question

i just got fox farms big grow...havnted started yet...plants just sprouted, anyway what i need to know is should I order big bloom as well, for when i flower? Do i have to get tiger bloom too? i just heard you have to flush your plant before harvest if you use tiger..... will they work fine without it?
Thanks....









Im a big fat liar!

I use all three of those big grow for ver. tiger bloom for beginning of flower then big bloom till harvest.... if you only get two. i would recommend big grow and big bloom
