Interesting. That is the formula I first made for my grower friends. I got it from a 420magazine link. It was a bust. I've since gone to the Sigma/Aldrich recipe which is many times more concentrated. The stronger recipe worked. Here's a link from phytotechlab; it's the Sigma/Aldrich formula in a very clear recipe.

I made my own silver nitrate using ACS nitric acid and a fine-silver coin. I have a lifetime supply.
For this recipe, do you dilute with water after mixing at a 1:4 ratio before spraying if so what ratio?
