Formula was KNO3 - 168 gr, C - 33.6 gr, S - 22.4 gr. Spectracide Stump Remover for kno3 (Labels and MSDS | Spectracide), Bonide 90% garden sulphur (http://www.bonide.com/lbonide/msds/msds141.pdf), Red Ceder charcoal.
This is just the components mixed into powder, did not mill, but thoroughly mixed after running through fine mesh. I have some I wet mixed that is drying waiting to be screened into grains. My main concern is identifying the residue.
Could it be from just not milling the ingredients fine enough? Or that 10% bentonite clay in the sulphur? Any constructive advice would be appreciated!
