Hi, Yesterday a few little spots appeared on two leafs. My seedling was very healthy and had a homogen green color, but now she has some spot... I don't know what it is. I didn't give them water when I usually do once time because they used to get at 10pm and I want to set the watering time earlier. So next day I watering them at 1pm. I'm sure it can't be the problem. Maybe nutrient deficiency? I never give them any as they only 8-9 days old (from emerged to surface). They growing in a BioBuzz light mix. There's a different spot as well, I marked it with black circle! Help please, these are my first plant. Thanks Royal Critical Auto ! And the full plant:
