I try to keep temps around 72-76 and i water them about ever 2 or 3 days in a 5 gallon potWhat’s the temperature in the room? And how often are they needing drinks? Maybe a picture of the whole plant and the container size would help too.
Definately some kind of issue with the leaves and tips curling down . Neither are a very good sign.They look like they could use more light. Other then that they look good. The bottom leafs looking like that is not a real problem ya can’t keep every leaf perfect I find.
