Hello! My Genovese seedlings have just germinated they are just about half an inch high. I am starting to see that their cotyledons have a kind of grey fuzzy look to them. Is this normal? I'm keeping them in a sunny window with regular watering.

Mine are prone to Downy mildew, but try getting them air movement, basils have long taproots and need deep pots, also, let them get totally dry between watering- and if you can, water them from the bottom, not the top. Basil loves heat and humidity, but needs good draining soil. Hope your problem gets cured!
