Q.discolored raspberries
Have 20% of ripe crop where berries are hard, white or pale on 1 side, 1 berry in a cluster might be ok and rest poor quality. Flavor and texture both affected. Problem getting worse every year. Dont think this is white spot as weather doesnt appear to be a factor. Plants in full sun in good soil. HELP!!!!
