Don't worry, sometimes they look like this in midflower...expect more colors soon

cool night time temps or sensecence. You've got "autumn" colors showing. this occurs in some plants without much help. In others it is exacerbated by colder night time temps -- 68F and below messes with plant biology and you get autumn colors. Looks low on N based on pattern of paling leaves. If the discoloration is caused by soemthing, it'd most likely be a K-deficiency, as that first presents in the margins and tips around the leaf. Looks reddish to me, so seems more likely to be natural plant pigmentation or fall colors due to temps/end of life approaching. Some plants put out some exotic colors, although rare.
