Dreaming in blue (first grow)

Your fine.. She looks great. She's a baby ..

She is searching for light so if you put her in a bigger pot she will continue to stretch until she finds enough light. Give her e bit more light and the stretching stops and you got the feeling she is gonna fall over place a stick for support. roots are very fragile at this stage so it’s better to let her fill the cup so you minimize the risk for severe root damage

Hey man. These arent pistils yet, these are the first nodes. Meaning that the plant is going to produce side branches from that node. And pistils later on in its life. Oh and you really shouldnt worry about your plant's health THAT much, it is called weed for a reason :P Most plants actually appreciate a good Care - Leave alone - balance :) (and a good overwatering, too. Just kidding, Im just that casual dude thats giving others tips on how to grow better but overwaters frequently lol) Cheers and good luck !
