using MG Moisture Control instead of peat for 5-1-1

If I use Miracle Gro moisture control as my "peat" portion in a 5-1-1, are there any changes I need to make?

1 - since it's "moisture control" will that affect anything, or is the quantity sufficiently small that it shouldn't matter?

2 - pH - since the MG mix is already pH balanced around 6.5ish, should I back off a tad on the lime (since natural peat is much more acidic)? Furthermore, I'll be growing trees in containers (for future in-ground planting), most of which are native to acid-soil regions (like Eastern US native oaks, maples, conifers, etc), so should I err on the more acidic side anyway?
