leaves yellowing on edges

  1. My plants aren't mature yet, but I noticed one plant had a few leaves with yellow on the edges. Is this over fertilization? I know it's not a heat factor
  2. humidity is too low... most likley not over noots...order a hydrometer and because of the cold winter in alot of places right now humidity is at as low as 15-10% some places...remember now doja is a tropical plant that loves heat and humidity...if nessacery gogeta humidifier and theyll Thrive.
