Growing Blueberries in 6.3 pH soil

I will attempt to grow Blueberries in a soil that has been made into very rich soil. Adding compost, wood chips, Fungal Slurries for several years.  
It had some Jujube in there that were recently transplanted (grafted Li onto Z. Spinosa).
It seems that the bacteria and fungi could help make the Blueberries get the proper minerals for producing fruit.  
I can add sulfur to the top every fall and let it become available to the plant in the spring.  In fact I had the blueberries in containers that had peat and pine fines mixed with good soil last year and it is time to put them into real earth.
Would additional iron and Manganese help?  
Any guidance on what additional I can do?

 The sulfur will keep you in the right P.H.  Adding some peat mixed with the soil at planting time will also get your P.H. right at planting time  4.0-5.0. Be sure to measure your P.H. a couple times a year for first year or two.
 Good soil life always produces a higher brix and/or nutrient level, but blueberries do good for me with no added anything. I dug in peat, and added sulfur for the first few years but the last 10 years they just produce with no help from me.
Their leaves mulch them, I just keep vines from growing into them.
