Just before flower you can do up to 40% and maybe another after the stretch. But looking at your pics id leave it alone, your plant will grow stronger with the extra leaves and that growth underneath will stretch up for the light. I also noticed that you might have missed the 'fuck i missed'. The cuts that ive done that have had best results were further down compared to what ive read in articles. About 3mm above the stem where it is juuust bulking up to your new growth. Looking good bro
