Mildew?

I removed two leaves at the bottom of Cassandera yesterday because I saw they looked sick, I realized that the leaves were sitting on top of the soil and trapped moister there.
I am afraid that it has spread a little and don't want it getting any worse or spreading the the 5 seedlings sitting next to her.

Here are some pictures

If someone could help me I would really appreciate it.

Thanks

WTF's a Cassendara?

It's her name.

I don't see any

I sprayed her with 60% water 40% milk

I also had some fun editing the photo I took afterwards. ...

She's looking better, a little dried milk spots on her, but besides that she's looking healthy.
The very few white spots I noticed have gone away!

Need to fix her environment...

Her environment is perfect at the moment.
She just had a small problem on two of her leaves that sat on top of the soil (as mentioned above) and after I removed them and sprayed her with milk she is already looking happy to me

Also there's a circulating fan in there too... so no hot spots accumulate.
