I'm about a month into flowering and a recent change in my work schedule only gives me 15 mins with my plants every day. Can I adjust the light schedule in 5 or 10 min increments so I can have some more time with them when the lights are on?

Lights are on from 6pm to 6am. I only want them to come on half an hour earlier. I need to be more like 5:30 pm to 5:30 am.
