1st Grow In My Life

First plant I’m growing ever from seed! The only one that made the pack was the white widow auto from royal queen seeds started 06/11/2024 using the paper towel method. I’ve been only misting it with water every other day until visibly damp at this point. I use a HGL 200 Retrospec lighting kept on 18 on / 6 off light schedule, planted in a 5 gal pot with roots organic soil. I started with being able to germinate 3 out of 4 seeds, 1 seed (green gelato auto) I will admit I entirely dropped and lost it in the soil so idk if it’s salvageable lol, 1 died and withered as soon as it popped after I planted its germinated seed (royal dwarf auto), and one seed I accidentally cracked when taking it out of the package so it never germinated (hulkberry auto) I’m kind of glad, not about the wasted , but for the ability to only have to take care of one plant for my first grow. I didn’t realize starting different strains would end up at different end points and I have only 1 (2x4x5 ft) indoor grow tent lol How do y’all think I’m doing? At what point should I use a root stimulator? I haven’t yet because the soil has organic nutrients from the start but I do want to see if it’ll help bulk my baby up for veg so I can start tying the branches down/manipulating the growing angle.
