what does .7 scale mean when dealing with nutes?

What does the .7 scale mean? I have seen it being used. I am using GH Flora series nutes and I have seen where people use .7 scale. Does that mean they use 70% of what GH schedule sheet tells you to use?

I have been giving them the amount GH says and my PPm is way over what they say it should be.
