i'd focus more on doing 3-4 sets per exercise, and less exercises. muscular hypertrophy is best with more sets than less. rep range is about right. stick to the basics, and dont bother with things like one arm db rows unless there is an imbalance or u simply dont feel the muscle with regular bb rows. training is simple, but as someone said, the diet really is key. u dont get enough protein, carbs, fats, water, etc = u wont gain muscle.
