Hello! My Thai constellation has these brown spots with yellow around them. I think it’s a fungal issue. How do I get rid of it?

How’s her soil?

#### PLANTS!!🪴🌱 replied on 2026-10-18

I repotted her today into a terracotta pot. She has a houseplant soil with perlite mixed in.

thai cons are notorious for catching root rot. maybe she needs a chunkier soil mix?

I checked her roots today. They were white, firm, and healthy.

Any chance it’s sunburn? With the season changing the sun is way lower than it usually is and I’ve had so many plants get burns because it’s sneaking in further than it used to. My monstera turned black in areas from its sunburn.

The window is not open. I got grow lights but it was there before. It’s gotten worse
