Progress

Oh the dreaded DIXY Cup.. I hate them. You did punch holes in the end for any excess feed to escape yes? Overall they're really not a good choice.. they're too small to start a seedling out in you'll be needing to change that soon and the 1st 2-3 weeks sound be left alone to build a root zone. The whole point of starting off in a smaller pot as opposed to a big one from the beginning in fems is to build root strength that will enable her to go through life with less issues Anyways. Good luck I'd just repot that soon. Or you'll get root bound Even cut the end off (the bottom). And put into a bigger pot. Then you just need to cut the side of the cup and pull up the cup (as stressless as an uppot you'll get. And she'll take off.. them cups are too small.

Transplanting that little thing right now will likely kill it because there's no root ball to hold the soil in place so it will just crumble apart and leave you with a battered and shocked little girl that will likely die. You can leave that little girl in there till it has a few sets of leaves before you attempt a transplant. At least that's what i would do.

TheUk420Show is right that it's best to transplant earlier than later. Your plant will stall out at 3-finger leaf set because of how little soil there is to make a root ball.

Hi buddy looks like your doing well but as the grower has stated its probably best of to transplant eraly than later as it will cause her bit more stress later on. I always try and start my plants in the medium they will finish in just saves faffing around. though welcome to the grow diaries community and congratulations at finally taking the dive and getting into growing you will find in a few months how rewarding it is to smoke your own cannabis and the pride in being able to say to friends "I grew that" hehe best of luck and if you ever need any questions answering about the site or growing my dms are always open buddy best of luck :)

Too bad if it was outside and it rained and the stem got wet.....it might just blow up into a million pieces!

You should transplant asap, a half filled tiny cup like that will stunt development dreadfully.

Looks good. Make sure to be very light on the watering. And don't let the water touch the stem. That cup will likely not need to be watered again for another 10 days depending on temperature.
