Purple Lemonade Auto; first grow

Germination: Soaked 15 hours in distilled water at 30°C, then put in cotton pads at 28°C for 24 hours. Initially, they should have been only 4, but since one wasn't opening at all in the cotton pads even when the other were ready to transplant, I launched another one. She must have wanted to troll me, because her root started to grow as I put the new one with her. I transplanted them in coco pellets presoaked in cal-mag water as soon as the tap root was about 1 cm long. There are then three of the same day and two other two days younger. Environment: In the coco pellets, I aim between 26-24°C and 90-80% humidity. I play them a few hours classical music a day, I want to put all the chances on my side lol Light: I turned the light a bit late, only as one started to open it's cotyledons. Normally you have to do it as the heads pop out.
