How is the different from a miracle grow product?

There is a huge difference. While the FoxFarm product is organic and made from earthwork castings and bat guano, Miracle Gro is a "salt" nutrient, meaning the elements in it are synthesized in industrial labs as opposed to just being worm and bat waste. Salt nutrients certainly have their place (they work wonderfully in hydroponics), but if you're growing in a soil-based system, it is safer for the plants to use organic fertilizers such as Big Bloom.

when do you start using and how often

Start using from the third or fourth week of flower (depending on length of flowering period for the strain). If in soil as sole bloom fertilizer, use 1/2 c per gal everytime you water. No need to flush before harvest. You still need high nitrogen in the first 2-3 weeks of flower as the plant stretches.

What water to concentrate ratio?

4 tablespoons per gallon of water applied once per week. It works well , but it's a bit expensive.

What is the NPK of this product (didn't see it in product description).

.01% .3% .7% low N seems key to this product, using it for Royal Blue Morning Glories. Started using it late in season but lotta blooms now. However don't have real control plant to compare...next yr!
