Unless it is an autoflower, absolutely do not do 24 hours of light with a photoperiod in flower phase... you will have a very high risk of causing a revege or some sort of repercussion for causing a major issue with the hormones inside the plant...
uninterrupted darkness is what causes / controls flower phase. do not fuck with the dark period of a photoperiod in bloom phase. no ifs, ands or buts and not a debate whatsover. based known science and knowledge that exists in the world...
One 12-hour light cycle lost is small potatoes, if necessary.
