Looks like phosphorus deficiency. Too much water can cause this or it is just purely lacking it. Good luck đ

In coco you can not have too much water in one sitting. Is your run off ph 5.8?

In the 3rd photo in week 12 there is spotting on the leaves. Does anyone have an idea of what that is from? A deficiency? I had trouble getting the nutrients right and that showed up first after I flushed for a few days.
