to the forum, Hcoe92!
Are the leaves "dropping" or drooping"?
Does the pot have a hole in the bottom? Roots need air as well as water and they can suffocate if there is no hole on the bottom.
How long has it been in that location? If it hasn't been there for a while, it may be losing unneeded leaves and is fine.
When you water does water come out the bottom? Make sure some does so you know it's moist all the way down.
Both over- and under-watering cause damage to the roots which causes brown tips. So does fluoride in the water.
