Californian Snow-auto LST Lucania weed

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!!

Hi mate, it is hard to see properly as the pictures don't show much detail but from what I see it just looks like a lack of nitrogen which can be normal at this stage. Maybe give her a little N boost or leave her as she is and she will be fine. Good luck and happy growing
