Scindapsus

[Hyacinth]

Hello all! I have a beautiful scindapsus here and am wondering about what looks like a powdery mildew or something? I noticed its leaves weren't looking so great...a few holes, brown tips, etc and I saw some white spots under the leaves. Nothing moving or what appears to be bugs crawling. I have applied neem oil spray every other day for about a week now so about 4 applications. The spots disappear when I spray but then come back. Just on a few leaves. Not sure what to do. Any suggestions appreciated!

Two things help Powdery Mildew thrive:
Periods of dampness or high humidity and being crowded where the air circulation is poor and the plants remain wet: The spores are also able to spread faster when they appear in clumps of their host plant. Don't spray water on the leaves at all, and allow the soil to dry before watering. I like to use an oscillating fan around my plants to keep powdery mildew down to a minimum. As long as its minimum amount of PM at this time on the leaves, changing the environment should be enough to keep it in check. However if you start seeing larger clumps of Powdery Mildew you will need to use a PM spray.

So this is a new plant as well...I've had it maybe 2 weeks and haven't needed to water it at all. It was so wet!! Its finally starting to dry out now
