is there problem with my blueberry bush
all the leaves on my emerald blueberry bush have these rust like marks. they were in neutral PH soil until recently when I put it in a container with a 50/50 mix of peat moss and potting mix.

Blueberries are sensitive to soil type. This can be easily corrected, though. Make sure you use a fertilizer specifically designed for blueberries. This will keep the soil conditioned to the requirements needed. If the soil remains too alkaline, then iron sulfate may be needed to bring the pH down more.
Blueberries will not do well in neutral to alkaline soil, so this will just take some time to recover and start to grow normally again.
