I didn't add anything when I took the pics but I just gave it some nutrients yesterday, all the new growth looks healthy. Hopefully this just blows over and doesn't affect them too much. I hear Blueberry is a sensitive lil' mo'fo. And it's in some soiless mix.
Looks like a bit of nute burn on the tips to me. I get that on the older leaves sometimes too. I've yet to use a pH meter, I just go by how the plant looks, and if the new growth is healthy, I wouldn't worry.
