The way your lower leaves are yellowing from the bottom (from week 4/5 veg) you look like you are just experiencing hungry ladies. The yellow is to even to be ph related. If you are in soil and have active microbes your ph will always be around 7 no matter what. I see you fed bloom and no grow nutrients your last week of veg. Just add a little extra grow on top of the bloom next water and she should start to bounce back for you. Happy Growing!!
