Yellow Leaves With Holes

Question

My NBC’s leaves look yellow and has some holes, what’s wrong? Fungal and over watering? The former owner told me it can’t be grown indoors (but reading posts here seems like it can? I live in SF) the plant just produced a bud so I assume it’s doing ok? But would love to keep the new leaves green! TIA.

I think that you have hit the nail on the head. Ovewatering and fungal issues seem to be the perfect fit for what I am seeing here.

They don't perform their best indoors. That is for certain. When grown indoors without supplemental lighting, they will stretch and grow long and lanky, as you see there. That isn't to say that it won't grow, but it won't look its best.

These are cacti, but they will tolerate a little more water than a typical cactus will. It still needs a thorough dry out between waterings. I would suggest, at least, halfway down the container between waterings.
