Dosage Guide for APT 1 (“APT Zero”) and APT 3 (“APT Complete”)

APT Dosage

Total Dose in 1 week: this is the important target. It is the cumulative total amount that you should dose in one week. Plants do better with more uniform access to nutrients, so achieve this weekly target by dosing daily or a few times a week. Precision is less important than consistency.
