Title says it all. I've always popped 'em in soil without a problem but this time I did canna coco flushed with water then charged with 400ppm fertilizer. All seeds but 1 popped out of 8 but after 2 days growth stopped. Cotyledons curled down and got brittle.
I figure it's 1 of 2 things that could have caused it. My light was too strong or the coco was charged too strong. I'm leaning hard towards the light being the cause, but I need some coco experts to chime in. I've never planted seedlings under this particular light and I think it was too intense for the babies. I think they just shriveled up. Never felt crispy clotyledons before.
As an experiment I pulled the dead seedlings and replaced them with tomato and lettuce seeds in 6 or so containers. Same coco. I've moved the plants under a light I always use for seedlings that is much less intense. If the lettuce and tomato seeds sprout and grow without a problem and keep growing I'll narrow it down to the light. If not then I'm kinda stumped. Maybe I should have started in rapid rooters or does it look like the light fried 'em? Sorry for the pic quality.
