Controlling your lighting levels will be critical as too much will cause algae issues. T5HO puts out a lot of light, especially if you have good reflectors in the fixture. Your slow growing plants don't need a lot of light. Ferts are good in modest amounts. My old low tech mostly crypt tank ran on low light, liquid micro+K nutrient ferts once a week, substrate ferts under the gravel, fish+fish food supplied the N+P macro ferts mostly and occasional water changes every couple of months when it started turning yellowish from organics build up.
