White Spots on Pea Seedling
I wonder if anyone here has seen this before? It doesn't look like any picture of powdery mildew I've seen. Two of my biggest seedlings are showing these white spots on their leaves. They don't seem to be affected by it but it's been worrying me. Last week I sprayed them with neem oil and the only pest I've seen on them is the occasional caterpillar. They are in a raised bed under shade cloth since it's getting too hot for them.
This picture is of the same plant.
