my recomendation to you is to forget the "advanced user addback formula (very confusing)" and just top your resevoir daily with fresh plain water, and change your reservoir every 7-10 days. 7 is better than 10 in my opinion. You can use a little Floraliscious too as a bud booster. Floraliscious is a concentrated organic supplement. It's strong stuff so use lightly. It also smells like a dirty fish tank so be warned
