Not a good start

Got some blueberry gum going very recently and after a good germination and planting they got to an inch tall all looking awesome and now have stopped growing and even are beginning to have their first leaves turn yellow WTF help! yes im a noob, yes i was probably a little anxious with starting with the little knowledge i have but i really would appreciate a mentor holding my hand through the process

Start reading. You have given very little info. Growing Medium, lights, PH, ventilation and temps just for starters. A picture would also help.

probably over watered or too hot/too much light

i've got them in rock wool with 3 cfl's and as for ph that's where i didn't pay close attention. using rainwater i assume that's gonna have a ph close enough to allow growth, am i right? besides that temperature is room temp and i got a fan blowin in there for ventilation. i'll get a camera to post pics (although i'll be embarrased to post if they don't get pretty :/ )

if anything with watering they'd be underwatered because i only watered them yesterday when they started to droop and the leaves perked right back up
