One of the many herbs I grow is chives, and this one sits on my windowsill beneath a grow lamp. They fell over a bit like the picture and they have white stuff inside the leaves. (and if you look super closely there’s some black dots and there looks to be a bit of tissue death) I’m expecting some fungal growth from this sample because it’s an organic sample, plus it fell over so it may have had contact with the soil in its pot which might have caused this problem. (plus it’s looking kinda sad)
Also, please ignore that it’s chives planted in a pot that says “basil.” It’s having an identity crisis on top of the disease crisis.
