Over the years I've gravitated to a single mix spread across all food plots equally. Some years they turn out better than others, mostly rain dependent in my opinion, but I know I could be doing some things better (ex. soil tests).

I have roughly 2ac spread across 5 plots....soil varies in all of them from red clay to rocky black dirt to sandy river bottom stuff.

Fertilizer rate of 400lbs of 13-13-13 per acre.
Every other year I spread 1000lbs per acre of lime into the plots....can't get a lime truck into my place.

Been planting a mix/per acre that looks like this.
30lbs oats
30lbs wheat
5lbs crimson clover
5lbs purple top turnips

I don't have a drill, so I mow, spray, fertilize/lime, disc, broadcast wheat/oats, drag, top sow the turnips/clover, pray for rain.

In the absence of a soil test, I'll get to it next year, what do you see above in my seed mix (or anything else) that needs tweaking?
