Yeah, it's fine. It doesn't hurt the plants or slow them down. Most people use 18/6 in vege. I use 16/8 in vege as you do. Hours of operation impact the power you want... If grow light is well-sized for the tent, should be 75% for 16h and 100% for 12/12 -- or 133% more when going from 16h to 12h. It's inversely proportional to hours of operation. Whatever worked well for 16h, simply amp it up 133% for 12h. Read up on Daily Light Integral (DLI) - wiki is fine... The gist of it is good enough. You don't need to memorize the math. There are DLI reference tables for that. 35-40DLI is a good starting point. You've likely already found a good light intensity through trial and error -- The plants dictate exactly how much power you should use based on how they grow.

You pick a day and change the light schedule to 12/12 no fussing around. Hermaphrodites happen when there’s an interruption in the darkness period or an erratic light schedule. When I flip to 12/12 my light turns on at noon and turns off at midnight. 18/6 lights turn on at 6 am and turns off at midnight. No stress man just flip to 12/12 and watch the show.
