Update 1: Got some great advice in the comments about seedling care from @Frigault and decided to hold off on nutrients for next watering. I've read before that nutrients should be introduced as soon as a seedling is above ground but it does make sense to wait especially since I've fried a seedling before (a full grown plant dose at that). The youngster hot a little taller on last check and her first set of real leaves are open.
I didn't get around to soaking the Amnesia Auto yet. I knock that out tonight.
Cana-Cheese is finally above ground so I've begun a 18/6 light schedule. She's looking pretty good too! I watered with a 1 teaspoon of CaliMagic and next I'll start with a super low dose of GH's trio with a low dose of Armor-Si. I'm a bit unsure if I need to let the Armor-Si sit for a while after adding like I've seen done with the powder so I think I'll play it safe and wait unless I find out otherwise. Also, I'm a bit afraid of her stretching so I'll lower the lights a few inches to see what happens.
A moment of silence for Dark Devil Auto. After a 24hr soak, the seed never popped (with the cute little root that sometimes looks like a goldfish tail). Just floated like her sisters did up to plant heaven.
I'm torn between taking a chance with my last one or trying a different strain. I did manage to get a Banana Blaze all the way to flower until she bit the dust. Going by advice gone bad, I fed her too high a dose of nutrients and she never recovered. When they say "listen to your plant", do it. Lesson learned.
