Has anyone ever encountered a whte fungus that grows ontop of the wheatgrass blades? It almost looks like a powder that if you run your hand over to brush it off it creates a white dust. It is making the wheatgrass turn a greenish-yellow and the blades are not as juicy as they once were. This fungus shows up the last 3 days of the grow cycle. I have been successfully growing organic wheatgrass for the last year and have not had this problem until now. I have tried watering less, increasing the airflow, watering with hydrogyn peroxide, and watering with baking soda.

Please help!
