Nutrient shelf life

So I've been outta the game for awhile (4 years) and I have the following nut's that were left over from my last grow:
BC Boost
BC Grow
BC Bloom
Awesome Blossom
Thrive Alive B1

They all have been stored down in my basement in a dark cool area, haven't been opened since the last time I used them 4 years ago. I know 4 years is awhile but do you think these are still any good? They are still a good liquid consistency and don't really have a smell to them.

So, could these still be good after 4 year hibernation?

Thanks
