Rock juice

Has anyone used rock juice the original one , not the organic one , it's one of the more expensive products I have brought and with not info on the back of what dosage , yes the guy at the hydro shop said 2 mls per ltr , which I would do at least 10 ml/ ltr but if any advice that would be great

Don't take this wrong, but,,,,,spending lots of $ on nutrient supplements that promise outlandish results are bound to fail to reach your expectations.......The simplest things work the best.....

On that note.....If it worked as they say it did. Why don't they make it any more?

I have heard that it is best to follow the directions as given....
