if u like then go from 24/0 to 18/6 then down to 14/10down to 12/12. doesnt really matter tho how u do it, i personally start from 24/0week one, then 18/6 from week two till five, at five weeks flower em on 12/12(cuz i have very limited hight restrictions). thats just my choice like cannabecea sed u can do wotever with the lighting, as long as wen u r flowering u dont interupt the dark period bcuz this can sometimes cause the plants to revert back to a vegetative state.
