Could this be used as nutrients in a dwc / hydroponic setup?

SInce it goes into solution easily it can be used in a hydroponic set up. Concentrations will have to be adjusted.

Does this contain micronutrients? Where can I get a detailed list of ingredients?

Ask the manufacturer for an OSHA sheet. All fertilizers are requrired to submit a full chemical breakdown listed for OSHA which must be supplied to the public on request. These sheets are requested by toxicologists in the ER.

Do you solve it in the watering water or are these timed release granules? The product image and the description sort of contradict each other.

This water soluble fertilizer feeds both the leaf structure, and the root system when applied as directed. It can be used in multiple spray forms,ie; a spray bottle or hose attachment. You can also pour it from a watering can, or a bucket, right on top of your plants. Hope this helps.

What country is this from?

It says right on the container made in Allentown, PA with an American flag . This is really good stuff....get some.
