Yellowing calathea

I have this calathea that has these yellowing leaves, it’s in the same room as a Stromathe, rattlesnake and lemon lime all of which have no issues with a humidifier so I don’t think it’s humidity. This plant also used to have spider mites that I’ve been treating with neem and soap and so far I don’t see any spider mites left compared to before. My next guess is nutrient deficiency or overwatering, what do yall think???? The pot has drainage and I water when the soil looks dry. It is 2 meters away from a south facing window
