I am new gardening and planted 4 blueberry bushes early spring (3 different varieties). I was thinking that the reddish leaves were just the natural change in the evolution of the plant but now I’m thinking it’s maybe a magnesium deficiency or lack of acidity in the soil? I don’t have a ph test thing and blueberry grow naturally in my area so I assumed I was okay to plant them without amendments. I am in zone 6b. What do you think? Thank you
