what up @savthegrower ! first off don't worry bro, you're in soil as it is, and it does have nutrients in it as it is. That mary jane, she doesn t actually like nutrients that much, hot soil might hurt her as much as it might help her - depends! basically you main goal is to make sure your seedling makes it into a big enough plant in the right amount of time. So when you plant your seed and it germinates, it stretches it roots outwards and downwards as fast as it can. eventually it will reach the bottom and the sides of the cup. If you move it to another pot before then, it will slow down your veg, just a bit (it's really not a problem, but it takes a bit longer). So it's simple actually : just check the cup every so often and when you see the roots at the bottom of the cup, then you should transfer it. The transfer is the most sensitive part of the operation, any time you touch the roots move the plant or otherwise abuse it in any way, you will shock the plant , and this will make it take longer. So what you want to do is prepare you soil, make a cup-sized hole, then take your cup and cut the bottom out and make a cut on the side of the cup. gently place the cup (keep the side on) into the soil, then remove the sides and cover the seedling with some extra soil. That's it bro ! hope this helps ! 🚀
