Questionable nutrients?

So I was doing some work for this old lady who loves to garden and happen to come across some bottled nutes (see below). My question is is there anyone who know how well these work and when should I use them in a grow?

What does it say on the back of the bottles?

Here’s the back

They'd work mixed at the right concentration.

seems like you'd be missing a lot of micro nutrients
