The only solution is to train your team. Put them in workshops and try to find out with what they are struggling the most. You cannot do it yourself at some point, the workload will be too much. There is no 10x developer outside of quick prototyping, especially if you are also managing people or projects and do software maintenance.

Very often work gets slow when goals are not precisely defined and developers have to improvise on the requirements. Micro-managing is bad but maybe their responsibilities need to be a bit stricter at first. With experience the railings can be removed.

Some suggest hire and fire, but if you don't put an effort into training you very likely will not find highly qualified developers or you have to pay extra.
