This is my timing too.
It fits in around me. I work 8-5, my son goes to bed at 7, I mix my nutes at 730 and I feed at 9.
Still got the rest of the evening to chill out.
I check my garden for 5 mins every day and when I feed it takes 30 mins.
I feed roughly every 3-4 days at present.

Although I don't have a son, the rest of this sounds almost identical to what I do.
I'm on 6pm to 6am... I'm up in the morning getting ready for work right at lights-off. I close the door to the storage area my tent is in at lights-off, and open it at lights on, just for better airflow when the light is on to keep temps down (temps at lights-on are 75).
I generally have a quick peek at the plants to make sure nothing is too close to the lamp, then do my work between 7-8. Five minutes on non-feed days, 30 mins for feeding.
