Some details – these are grown for research purposes in a greenhouse w/ AC and heat, so the temp isn’t an issue. We grow the Mimulus in big 10×5 trays that are flooded every few days to water. We follow the same process for a bunch of different species of Mims, but only these ones seem to be having this issue. The plant continues to survive and the upper leaves don’t seem affected.
I’m experimenting with more/less water on a few plants to see how they react, but these guys can grow just fine in standing water, so I don’t think it’d be a watering issue.
Curious as to what yall think!

Looks fungal. Try adding small fans to reduce humidity.
