Onion

Question

Why are the tops of my green onions, that are growing from seeds, turning a light brown color, like hay? It’s just the very tips of the 2-inch sprouts that are discolored.

Answer 1

Brown tips would indicate an environmental issue either with water (under or over-watered), temperature or lighting.
