I grew a batch of White Rhino from GreenHouse seeds recently, and was extremely dissaspointed with the final result. it didn't yield nearly as well as advertised although it was a decent yield, it wasn't what i was hoping for. Anyway, i digress....I took the buds to a dispensary to vend and the guy said he could tell i used botanicare cal mag due to the smell. He told me not to use their cal mag bc it takes over the smell and taste of the bud no matter what strain. What cal-mag additive should I use to have residue free buds. Also, what nutrient lines should I use? Kyle Kushman suggests using Canna...
