based on growdiaries.com/diaries/123752-grow-journal-by-hideandfly looks like good internode length to me.
If you think the internode (fancy name for space between nodes) is too long, you can increase intensity of light -- turn it up or get it closer if it doesn't slim the coverage of course.
looks great -- training it and using scrog will help keep good spacing and good airflow... hard to go wrong if you keep it up.
