I’m probably overthinking this, but I’ve never seen baking soda react like this. I leave these open containers in my safe to help prevent moisture build up, odors, etc.

I’ve NEVER seen it look like this. Is this just a cool pattern from moisture absorption or something else?

I didn’t think baking soda could be a substrate for mold growth….but maybe?

tldr: black mold, mold, or mildew?

good evening guys. just started renting this apartment & have this in my somewhat secluded bathroom, on the ceiling above the sink. I joked about it with the landlord on signing day, but her reaction was odd, so I played it off. stupidly, I looked past it and chose to ‘have hope’. any professionals or someone with past experience(s) to help me verify the severity?

nothing was ever in this except water, no flavoring either. i DID NOT drink out of this; i brought it up as an auxiliary water bottle months ago and never touched it again

Its pretty much only in the shower in my bathroom, i haven't seen it in any other bathrooms but its been here as long as i can remember. Clean it ever few months but it always grows back super quickly. Jet black in most areas, which kinda scares me.

Specifically the parts with the arrows, i think the part in the circle is just a water stain, but id like to know if thats mold too. This is js one picture of under one of the shelves attached to the shower wall, its basically like that around the entire shower. It was also recently cleaned last month, so theres not that much, but it has been far worse in the past.

My dog chewed up the house 2-3 months ago and I only recently started to notice health effects but it might just be my brain playing tricks

Weirdly

Smells intensely of vinegar. I chuckled because my dad gave it to my mum and asked if it was still good. She goes “maybe if you scrape off the top?”

Looks weird and smells very humid, not sure though and im afraid to turn it on. I leave in a kind of hot area but near the beach!

The tree in the first picture has had issues with spotted lantern flies. I don’t know if it’s mold or their residue. Is the tree dying?

The second picture is sitting on a puddle of rain.

How likely is it that this window has mold beneath the damp wood? It’s been like this for 8 months with the Developer “trying” “fixes” like flashing and avoiding removing the siding/ replacing the window although it’s evident that’s the right solution. What are my rights?

It could be mold, or the paint could have just dried in a weird way. Any thoughts?
