Hello. I got this Dracaena Janet Craig from Lowe's almost two weeks ago. I have only watered it once since (after making sure my moisture meter read almost dry in a couple of spots). I am planning to move it to a new pot since I noticed roots coming out of the bottom of the pot and can see roots on the top as well but I wanted to wait a few weeks until the plant got used to its new surroundings. A couple of days ago I started seeing brown spots on the leaves with yellowing halo around it. I have attached pictures. I love this plant and hope I can mitigate the problem before it gets worse and I lose more leaves. Any help and/or advice will be appreciated. Thank you.
