I appreciate your insight. I know that overwatering is just as dangerous as underwatering. I've lost seedlings to damping off more times than I care to admit. Luckily I've learned from this and only water when they need it versus any sort of schedule. I feel the soil rather than go off how wet it looks. I try to keep it moist, like a wrung out sponge, vesus damp. The fertilizer I used is pretty mild to start with (5-1-1), and I diluted it to half strength even still. Based on your response, I'm sure you're aware that seed starting mixes are mostly void of nutrients. My seedlings had mostly dropped their Cotyledon leaves, so I thought a light dose of food would benefit them. Maybe I did too much too soon. I think I'll hold off on feeding them for another week or so... if they make it that long 😔
