plants look hungry with the yellow starting from the bottom and moving up. Feed more.

Couldn’t yellowing from the bottom up also be a magnesium* deficiency?

magnesium is semi mobile in the plant, so it would not just present at the bottom... it would show up in random places all over the plant. There could be some of that going on too, but the overall yellow from the bottom, moving upward, indicates a macro nutrient deficiency, ie, they are hungry.
