my leaves r starting to get like light brown or tan discolored spots, any thoughts on what this could be? I thought maybe it was like burns from the light but Idk?
It could be many things. If you posted pictures it would help a lot. Tell us more information, such as what type of light you are using, how far away from the plant it is, temp in room, growing medium ect..
But the leaves could be getting burnt. When you feed your plants "assuming you feed them" make sure that all water droplets are off the leaves when you are done feeding or they can burn little spots on your leaves and eventually kill them. It could also be bugs, check the underside of the bad looking leaves and the leaves around it to see if you see tiny bugs. Or it could also be nute deficiency if you are not feeding them.
Throw up some more info and we will try and narrow it down for ya
