Pruning will not correct this issue, unfortunately.

The first thing to do will be to test the nutrient contents and pH of your soil. My first guess is a deficiency of phosphorus and magnesium, but this can also be caused by a pH that is way too low, as well.

If your soil tests are normal, then you may have a moisture issue. Wet soils that do not have a chance to dry out between watering will suffocate roots. This will prevent roots from taking up nutrients.
