Wedding Cake mainline (Norcal Farms)

At this point I had my exhaust fan and carbon filter set up and I'd cut a passive exhaust hole so I had negative pressure in the grow tent, which I like. I got a little turbo fan and was pretty happy about the humidity which was consistently staying around 50%. I was noticing that there were light colored bands or stripes between a lot of the veins of the leaves and some of the lower leaves were turning yellow. It reminded me of leaves going yellow during harvest. I started keeping a closer eye on my runoff pH and used apple cider vinegar as a natural way to adjust it before getting pH up and pH down from the store.
