You know, this is exactly what we need to see though. If AN says to not use Cal/Mag and we still see deficiencies in our test grows then that is awesome, in a bad kind of way. You were the guinea pig but there will be many that learn from this grow. As is the case with almost every grow, different strains are going to have different nutrient needs. It was apparent the TD doesn't need that much early on and can probably be run on the standard AN regime but the Cheese is going to need those extra doses. You are laying the groundwork bro! Nutrient trials in action.
