Try have a little clean up day 42 not nothing major but enough for light to hit your buds apart from that look okay how much you feed at time and are u in coco?
Your gunna wanna take some leafs off also need 12h darkness 12h light day 36 buds will slow down growing soon but you will get something back just not as good and Yh 70% to high can cause mold so watch out hope this helps abit
