no it wont affect quality.
flouros have very poor light intensity and they need to be close as possible without burning and this is even more true in flowering than veg where you may want to leave a few inches so they dont actually grow into the bulb before you have time to adjust them, this is also really the determining factor on your yiled if you had the space you could veg for a few more weeks but you still wouldnt have the lighting or space to take advatage of the extra growth so it doesnt really help your yield in your case.
personaly would start lst training them and switch to 12/12 now and hopefully you will have atleast a couple of males to remove within a couple of weeks to free up some space and finish training the females through there stretch phase of flowering trying to keep the canopy at an even height.
