Depends on your conditions, if you can increase airflow, or reduce rH, I'd probably push on. More fans, defoliation... 40% lights on can hit 60% lights off. If it's an auto, you could cut the dark period out completely as well.
If I could change something I'd probably chance it, maybe clean out some of the nurfle. If I couldn't, I'd be looking to cut early and save what I could.
