Does it make sense to switch dual light HPS to full flower HPS after 4weeks bloom?

Sounds a bit petty, but Maybe you People have got some information/experience to share for me

thanks in advance

you mean because of the light spectrum? i think thats a great way to go. i dont use hps but i know white spectrum will make a plant stretch less than red but red its the one that the plant uses the most specially in flower so changin the light right after the stretch just in time for the heavy flowering seems like a great idea. dont take my word for it, check on youtube many spectrum comparisons and side-by-sides for you to evaluate and make a choice
