19-4-23 powdered nutrients

has anyone here heard of this stuff or used it. States that it can be used from veg to flower.

The cost has me intrigued because we all no advanced nutrients is not easy on the pocket book

I did see one guy posting here about it. I have even found a Facebook group that’s named 19-4-23. They all post great things but I’ve heard that before

Jacks nutrients does the same thing, so it may work.
