I use a mazzei injector. Not nearly as high speed as what you have. Generally, I use a product called Brown's Fish Hydrolysate(OMRI listed). Depending on the soil or plant tissue analysis, determine lbs of N or P or K needed; any land-grant university will supply recommendations with their analysis or you can google different charts. It is important to note - P should be applied prior to planting, if deficient. You need to know your flow in GPH and suction of your device to accurately determine how much product should be diluted/injected. I am not that familiar with the mix-rite but would assume you can adjust settings.
Any good irrigation supply store should have a someone who can help you out. University of Georgia and UNC have some pretty good fertigation schedules but most of the time sites differ in nutrients needed. In that case it is just a few math problems. Base it all (per acre) as you will find more data in that form and may not have to reinvent the wheel.
Also, with most Organic/ Omri listed liquid fertilizers. You have little chance of pushing enough to do devastating harm. Hope some of this helps. If you are more specific in what you need, I maybe able to clarify.
