Growing Plants in Coco Coir ... you may may find that coir does not work as well for acid-loving plants, such as azaleas and blueberries. Coir can also be far more user-friendly than peat moss or rockwool.
Coco-peat fiber facilitate excellent lateral water distribution for the benefit of berry roots.
Rockwool is a volcanic rock heated to extreme temperatures to fluff it out and it has been used in hydroponic systems for many years and is extremely popular with some growers as they feel it is the best media, but has many drawbacks; Not environmentally friendly and hard to dispose of.
Dust and fiber are a health risk.
pH is naturally high which requires adjustment by the grower.

Q. Bluberry brown marks

Why are my blueberries getting marks that are hard when blueberry is opened?

From just this image; it can be hard to tell. You will want to do careful inspection of the plants; leaves, stems of the Blueberries.
I suspect this is an Anthracnose: which can be treated by use of fungicides.
I've listed some articles to help you with diagnosis.
You also could take some samples to your County Extension Office, they may have more information on regional issues in fruit crops.

Q. Wild blueberries

I have thousands of wild blueberries the low and high bush. I rarely ever pick the low bush..and when I say thousands I am not joking. Anyway, I pick blueberries every year but for the last 3 years they have not produced much at all..last year there was some, but the year before that there was none, and this year there are none, and there is no way that I can fertilize or prune etc. as they are in the woods. Of course there are thousands of them, so imagine that task and cost…I was wondering, do they go dormant at times for a few years? We had a pretty cold winter and there has been plenty of rain and sun this spring summer and plenty of bees around There were a lot of green berries but then nothing –  no blue ones and no green ones either. Where did the green ones go? Thanks for any help. Bonnie

Weather, sunlight, disease or even birds and pests can be reasons that you are not seeing berries.
You can talk with your County Extension Office to see if they have weather reports on other crops in your area; you mention some weather extremes.

You may be picking the fruit too early. Do not pick them as soon as they turn blue. Wait a few more days for them to fully ripen and grow larger and sweeter.

Also, follow the fertilizing schedule in the article below and the importance of acidic soil:

Q. Dwarf blueberry

Can you grow dwarf blueberry plants in big pots?

Answered by

Yes you can. I don't see your planting zone listed, but it's best to have at least 2 zones colder than yours if you keep the pots outside during the winter. For example, if you live in USDA hardiness zone 7, you want blueberry shrubs that are cold hardy to zone 5. If you don't have that buffer, you can move them to a protected area such as a shed or garage for winter. Here is more information:

Q. What is the mixed soil material for blueberry plants?

The ingredients are easy to get and not expensive

Answered by

The important part of the mix is two things. Ammonium Sulfate, rather than Ammonium Nitrate- Blueberries are very sensitive to nitrates, and using any fertilizers with nitrates will result in discolored plants, and eventual death.

The pH must be a little on the acidic side as well- Blueberries don't really like neutral to alkaline soil.

The good news is that Ammonium Sulfate will lower the pH of your mix. You, sort of, kill two birds with one stone.
