How should I present a weakness without creating a new concern?

I actually think your weakness is a good one! However, your mitigation is not great. First, you need to have already mostly mitigated it (i.e. you don't really have this problem anymore). Secondly, regularly asking for feedback triggers me/an interviewer to think "oh no, I'll have to micromanage". Rather, have a better set of steps you take (i.e. you're better at identifying what work should/shouldn't be done, better at delegating, etc. etc.)
