peyote red spots, please HELP!

[Artefacto]

I recieved this peyote 9 days ago, I didn't give it too much light the first and second day, I started giving sunlight through an onnion paper at the third day, removing the paper if the day is cloudy/mostly cloudy. After the 7th day these oxide red spots were noticed, does anybody know what's happening to the plant? is it sunburned maybe? does a fungus attack look like that?



thank you so much for your help, I include a picture taked the fifth day (before.jpg) and another one taked today (now.jpg)
