1/8 teaspoon is certainly far too much. Quite a while ago in CPN
there was an article giving safe concentrations for CP, however I do
not remember exactly since I am using a home brewed fertilizer for
some time now after Miracid was hard to get in Germany and the pack I
had got wet because I did not close it properly.
This (our fertilizer) is based on the analysis of Miracid with some
minor changes. I add very small doses in the water which is used for
misting, watering and the fog-system.
