Actually I don't think the chips changed pH where I used them. I had a very productive veg garden where I used a huge amount. Other ornamental plants are doing fine.
I'm not sure how much nitrogen is 'drawn out' to break down the chips, in comparison with the multiple other nutrients 'added in' when the chips rot.
The 'nitrogen draw' from hardwood chips didn't stunt our pittosporum hedge, which went from 1 gallon plantings to 8 ft tall in 3 years.
To add nitrogen fast, plant Clover, then rototill it under, if you don't want to add a commercial nitrogen fertilizer because of being totally organic.
If something seems to be flagging, Compost Tea will help. (In a barrel of water, use 10 gallons of deciduous leaves, a quart of fish fertilizer, and a cup of molasses. Marinate a week, then pour on a bucketful as needed.)
The other location - where I'm making it inhospitably acidic - is under the Live Oaks. I even add the neighbor's oak leaves which they raked off their lawn. Oak leaves are nutrient rich, just slow to break down. For a few months, leaves contain phytols that inhibit seed germination.
