As a manager, it is normal to be more directive with someone who is underperforming due to (perceived) lack of knowledge. You do need to be clear about you doing so though, and be clear about the path away from it.
I had a manager a long time ago who did it in a nice way. Our office was underperforming compared to the other offices he was managing, so he explained to everyone in an all hands meeting that he would be spending more time on control activities with the goal of getting back to not doing so once we were hitting delivery targets once more. No-one took offense to that, it was more "Ok, we are not performing at the level we need to be, and that means we will spend more time on control activities for a while, but to get out of that and back to our normal more laid back approach we need to do X, Y, Z."
The harmful situation is when you start spending more time on control activities without expressing why you are doing it and without explaining what the path out is. The responsibility for that is for sure on the boss, but also on the employee. If you are not asking "Ok, I have noticed this, why is that?" as an employee as well, then you are contributing to the situation and the downward spiral.
