Blueberry plants weakening, and/or dying
A few of the plants, which I send to you as an attachment, are weakening, and I am afraid - dying. There are a number of reasons why this could be - maybe the harvesting is a big burden for them, considering we planted them in November 2016 (they were three years old, 5 liter pots). The producer from Netherlands told us that there is no reason we should remove the flowers and crops, so we did not. The plants looked great up until a week ago, when about 1% started weakening (they are easily spotted, because most of other plants look perfect, but I am afraid that this number will rise).
I will also attach the water analysis.
