Broccoli plant has white spots?

[luvshelio]

I have this broccoli plant and it was growing amazingly even has 3 broccoli’s growing. It’s been rainy weather and I saw these white spots growing in the edges of the leaves. Can someone help me? Will it spread?

Probably caused by staying too wet. It doesn't look like a fungal disease. Maybe it will stop raining so much.

Have you had a soil test? The problem could be a boron deficiency as your photo looks similar to broc I have seen with a boron deficiency.

Not a fungal problem but looks like a soil nutrient deficiency to me.
