Being a chemist, it's pretty natural that your first inclination is to treat with a chemical (believe me, I understand - I've worked in the chemical industry for over 35 years), but that is treating the symptoms, not addressing the problem. If you must do so, and can't wait for the Physan, one ounce of bleach per gallon is the appropriate rate, not 10%.

I'm with Catt - don't use cinnamon on roots. It's a marvelous fungicide, but it's also a desiccant, and can be damaging.
