Dove orchid leaves with brown streaks

[mkampf]

Hello-Thank you for the direction. I obviously do not know how to use this post, mia culpa.. I have only had this plant a month and it is potted in a 4x3 pot with what appears bark material. There are 3 (2 big and one small bulbs) in the pot. If I can figure out how to attach a picture, I will send.
I have been watering from a watering can about 3 times a week and check with a moisture meter before watering. The meter says it is completely dry before I water. I let is sit outside facing eastside -sun directly on leaves (I can move to more shaded are if needed) and we live in upstate NY. I bring in at night. We are running air conditioning and wondering if the drastic temp change in the evening is having a negative effect. There are about 2-3 long (2 1/2 feet) leaves each bulb and they are turning brown and shriveling. Please help me save the Dove..Thank you..
