Hi, who here uses API Leaf Zone and how often? I know the label says once a week but some of my plants seem to be lacking severely in iron, and I would like to up the dosage to once every 5 days.
I may do that since i have a bit of a lightning problem and I can't find the bulb I'm looking for. Currently I have 1 wpg in mine and some of the plants have holes/yellow leaves.
