Where do you live? that is always a key requirement in answering plant health issues.

However, indoors and oak tree is an oxymoron.

Yes. The oak MUST be outdoors. If you live in an area with very cold winters, you may have to bring it inside (to a cold garage or porch) for frost protection, but if possible it should be out all the time.

You note that the changes have occurred during the last 5 days. Does this mean it is a new tree to you?
Did you buy it? What kind of oak is it? What soil is it planted in? And yes, where in the world are you?
