I got this variegated cactus 3 weeks ago. When I first got it, it was yellow with hints of green all over. Mind you, it's from seed on its own roots.
I repotted it, slightly watered it, and have it on my warm windowsill with my other cacti.
Since then, it's lost almost all its green color and gotten golden yellow with slight specks of pink!
There is no sign of rot, roots are healthy, plant is firm and spiky spines, no sign of anything wrong except the color change.
What's going on!?
