OK. Stop and think about that "twice a week" recommendation: Why? What would make that plant have different needs than any other?

I feed my plants - all of them - K-Lite 3 times a week, at very low dosage. If I fed them 1x/week, I'd triple the concentration of the solution, resulting in about the same amount of food applied.

K-Lite is intended for regular watering, SOLO, being a combination of fertilizer and KelpMax stimulant, is NOT intended for regular watering. It is intended for the grower who really doesn't want to "mess with" their plants too much - applied every two weeks, with plain water in between, and the plants will get about the same treatment I give my plants, only with less detailed effort.
