Seedling woes - Coleus
I successfully germinated 15/15 Coleus seeds last week and promptly put them into a light box (nothing else is in there).
They looked dry so I gave them some water a day or so ago.
I got home from work today and one seedling's leaves have curled up a bit (which I think might be due to heat of the lamps so I've raised them) and another has collapsed with the base having become damaged / perhaps with damping off. Or just too much water?
It's quite disheartening because I went to good lengths to do everything right including sterilising everything. And I know I am a serial over-waterer so made sure I only watered when the top of the soil seemed dry. Do you think it's normal that one or two seedlings just fail like that?
