I purchased a Palm Tree about two months ago (pictures below) and I have noticed that it is starting to turn brown on the ends of the leaves and have also noticed brown spots as well as the leaves drooping/wilting. The palm tree is 7 feet tall and was purchased from a large palm tree supplier who potted it for me. From what I have found out online, it's either due to under-watering, over watering, or humidity level. With it getting warmer outside I do have the AC on, however the house never gets below 70 degrees. I water it twice a week, a little more than a gallon each time out of the tap. The palm gets sunshine several hours a day where it's currently placed at.
Any advice will be greatly appreciated so I can save this tree before it's too late! Also, what type of palm tree is this?
