Marigold doesn’t look right
Why does my marigold have brown flower buds that look like it didn't grow? Is it normal? Or too much temperature? I put my marigold in a pot outside my house with direct sunlight.
You have a number of nice flowers, so I guess you're concerned that some of the buds don't seem to be opening?
