I was solo.
No issues! I cried a little at the potential hose damage though.
What concerns you've read or your local divers expressed seem the most relevant to your situation?
A possible side note: a question regarding solo multi tank diving might be better suited for the advanced forum.
If it's a basic question, my answer would be the dive would be best called. In the case of equipment failure the dive is over unless returned to 100% functional.
Cheers.
