Nope that would cause them way more stress than needed if you rreally arnt happy with them and want to go back to veg just swtich the lights back to 18/6 but keep in mind she will most likely herm if you do that and if shes does not herm she will probably be stunted by atleast 3 weeks while she converts back to veg and she will have some very strange growth on her too like mutations this can benefit us sometimes in a process called monster cropping where you take a cut from a flowering plant and force it to veg and then flower again this causes all sorts of abnormal growth multiple tops ect. Though its upto you I would just let her finish my friend your already doing a great job :) If its not broke dont fix it :) 👊
