orange and red leaves on blueberries #641903

Asked May 27, 2020, 3:06 PM EDT

Hello

I need help diagnosing problems with my blueberries. The young leaves are reddish and some have chlorosis.
What could be the cause of this problem? Can the problem with the leaves occur because the soil has a high pH value or there is not enough food?
Can a pH value below the optimum make a problem as well?
What value of EC (electrical conductivity) should be in the root zone in the substrate and in the soil in order for the blueberry to function normally and have food for its development?
Attached I am sending a photo of a blueberry with a problem?

best regards Nick

Could easily be a soil pH problem. Blueberries need an acid soil. Have a look here for more information:
