Fox Farms grow big questions

Hey i have two questions about FF grow big for soil.
I have a bottle that has not been opened until now but its been sitting for 6-8 months. will it still be good?
Has the color changed of grow big? my last bottle was a dark brown liquid and it looked like watery molasses. I opened this bottle shook it up and its green.

Not sure if it can go bad.sorry
Grow Big does come in GREEN.
Their Big Bloom looks brown.
Hope this helps....

Peace

the grow big is supposed to be green not brown

Was it left somewhere hot? Read the bottle

fox farm grow big and tiger bloom are both green except foxfarm bigbloom its a dark color looks more natural
