Hello
As it is your first grow I suggest to start in DemakUp cottons and put them in soil when you see the germ.
Using nutrients in this early stage is not really recommended... I know how new growers could be excited to use their nutrients like Masters ... I personally use seeds boosters and roots boosters, like trichoderma, mycorrhizae, lignosulfonate on young seedlings but never nutrients ☝️
A young seedling doesn't need nootz as she gots everything in the cotyledons ( called feeding leaves or embryos ). But you can boost seedlings with roots boosters with no problem for your young babies.
