title: Lumen Debug Log not working as expected
body: <p>I'm using Lumen 5.3 and I'm not sure on how i should implement debug mode.</p>
  
  <p>In .env, i have this:</p>
  
  <pre><code>APP_DEBUG=true
  </code></pre>
  
  <p>In my script I have this:</p>
  
  <pre><code>Log::debug("Test"); 
  </code></pre>
  
  <p>So it will log in storage/logs/lumen.log when i run the script which is right.</p>
  
  <p>I have made the value of APP_DEBUG=false and yet the Log::debug line I put keeps logging in lumen.log. How to turn off the log in debug level or is any other way to implement what I'm expecting to happen? </p>
