Ok so I know little to nothing about plants and my mom (whom I normally ask is 2 hours away). I have this tree that I found just as it sprouted from a helicopter seed this spring. I don't know exactly what it is (assuming maple?), but I'm worried my little guy is ill.

The tree is kept indoors in a pot to prevent it freezing outside. Inside the pot has of course soil and some hay/grassy stuff my mom put in to help me in case I over water it. I keep the tree in a south facing window, and it has been inside since September or early October at least.

Today I noticed some discoloration in a couple of the leaves and I'm wondering if I should be concerned. I have a couple photos. Please let me know if you have any questions. Thank you for the help.
