bio-bizz grow and bloom nasty smell!

Hello fellow pot lovers,

I am currently in the flowering stage of my grow and am using bio-bizz. There is an awful small in my growroom and I think its this stuff. Should I be worried and will it affect the outcome of my crop.
If anyone knows then please help me!
Cheers

I'm using Biobizz half way through flowering stage and my plants smell like heaven.

Mine look the part but have very little smell, do you think there is something wrong?
