I agree dont pull the leaves very much needed for photosynthesis thats the access point for the non-mineral nutrients found in air/water we know of as hydrogen,oxygen, carbon which in simple terms the leaves turn into starches and sugars for the plant. 16 essential plant nutrients 3 of them are mainly through the leaves you remove that then your removing nutrients then the law of the minimum kicks in which shows you how important environment is as well.
Keep them on and like bigsteve said remove only the dead leaves which are usually at the base of the plant, you have to lollypop and train early you need her to focus on flowering this late in bloom but I have cleaned up the bottoms before like removing small bud sites and leaves late in flower ,it caused a bit of a delay in the finish so now I just remove the bud sites not getting light and leave the corresponding leaf.
