Still trying to get humidity ironed out in that room. I'll start nutrients once I get a real leaf, I'm thinking GH Maxi series because I wanted to keep my first grow as simple as possible, and that seems pretty darn simple (and I've had good luck with it for other plants).
Day 10: Started watering with nutrients since I've got some serrated leaves. Using a blend of MaxiGro, Bio Roots, and CaliMagic because... that's what I have on hand (from other gardening). I'm open to suggestions or revision, I just wanted to keep this first grow pretty simple. Day 10 Update: Whoops! Just realized the full nutrient schedule lists a different amount for seedlings than what's on the bag! Good thing I caught it early. They'll just get one day of turbo nutes.
Day 12: Checked roots and they're healthy little buggers! I probably should have moved them to the next pots a few days ago, but here we are. Moved them to ~12oz newspaper transplant pots with buffered coir and rice husk. Roots looked healthy.
Day 14: The very tippy tips of the biggest leaves are looking a bit burnt, so I just gave water today to flush and in case they're getting too much nutrient.
