Is there any detremental effects to adding micronutrients to the tea at the end of brewing, just before spraying on the plants?
the ones I am specifically asking about are

Manganese sulfate (32%)
Zinc Sulfate (35.5%)
Epsom salt- magnesium

I would like to add them seperately (different applications), and only 1-3 tablespoons per 40 gallons of tea.
Am I destroying bugs with this, or should i apply a foliar application seperately?

Thanks,
Phil

Phil,

Haven't seen any testing on this, and I'm guessing in low rates the microbial loss would be minimal. Best thing would be to get a hold of a microscope and look at the tea before and after. If you want to err on the safe side, you could do them as separate applications though.
