A local daffodil grower in Nashville TN is wondering what could have caused these spots on her daffodil. I thought it might be poisons or chemicals, but she said nothing has been sprayed near the daffs. Any thoughts?

Those could be fungal or bacterial infections, freeze damage caused by a wetted water droplet freezing through the cell walls or the weirdest one I have seen is droplets of water being a magnifying lens burning the cup tissue. If you have a high power hand lens you will either see the bacterial rot sludge, fungal hyphae broken epithelial(skin) cells from the freeze or perfectly fine cells just a different color.
Thank you for your reply, Michael. I have forwarded it to the grower of the flower.
I agree with Mike a visiting insect may have visited and left a deposit of
fungus or the spots could be bite marks again leaving deposits.
