Hi grams per liter or quart?

I come up with 1.19 gram per quart of water. At 1 teaspoon per gallon. 4.76 grams = 1 teaspoon. 4.76 divided by 4 quarts. I Goggled teaspoon to gram conversion.

Does this have micro nutrients?

Yes as noted in product description: Guaranteed Analysis Macronutrients: 13.0% Total Nitrogen (Nitrate Nitrogen 12.5%, Ammoniacal Nitrogen 0.7%) 3% Available Phosphate Acid (P2O5) 15.9% Soluble Potash (K2O) 8.0% Calcium (Ca) 2% Magnesium (Mg) Derived from calcium nitrate, magnesium nitrate, potassium nitrate and monopotassium phosphate Micronutrients: 0.177% Iron (Fe) 0.088% Manganese (Mn) 0.044% Zinc (Zn) 0.044% Copper (Cu) 0.018% Boron (B) 0.018% Molybdenum (Mo)

If I use 1/2tsp per gallon of water, do I use it to water once a week?

That's how I've been using MSU Orchid Fertilizer for years. I was given the old trope, "feed them weakly weekly" and find it's good advice. Half label strength once per week.
