OOpsie. I re-read the directions and it did say teaspoon not tablespoon.
What I plan on doing with the KLN mix (1 gallon water to 1 teaspoon of KLN) is make sure my phals are established in S/H first for a few more weeks, then start using fertilizer 1/4 teaspoon per half gallon and a drop or 2 of Superthrive.
