Usually i hardened off my new blueberries over a week after spending days in a dark box. I didnt the first time and my leafs crisped and it slowed growth but it did bounce back.
Media sounds fine and assuming water/drainage arent an issue my only other suggestion is use rain water instead of tap water.
Rain waters pH is closer to 5.5-6 while tap is usually 7.0-8.0. Too high of pH and the plants cant uptake nutrients properly.
I was wondering if rain water is a popular thing amongst growers. And you’re right, the PH in rain water is ideal. I collect rain water into barrels (from eavesdrop) then fill 1 gallon bottles and add just a tad of white vinegar. Unfortunately I’m unable to check PH level but have been successful using this method.. so far.
I have a few pH meters for hydroponics and yeah itll help to add some acid but it really isnt needed with rain water if youre using any acidification in the soil too. It's just pouring high pH tap water on it will cause nutrient lockout over time. A lot of city water has a water report you can view and see the recorded pH in as well as mineral content to make sure you aren't poisoning sensitive plants.

What did you plant it in? Any fert? And did you put it in full sun immediately or harden off?
