Am i doing it right?

Hey guys,
im new to the website and thought itd be nice to see if im doing everything correctly,
i got 1 blueberry kush plant thats 3 days old and it about 2 cm tall, im using a regular fluorescent light, 120W and i keep it about 2-3 inches above the plant, i have the light on for 18/6, i dont have a timer so twice ive been an hour late to change the lights, is that bad ?
Its in a box thats 14" x 14" x 21" for now, i know im going to have to move it when it gets bigger, when should i move it ?
when should i start giving nutes ?

there are guides on this site which are terrific, which great growers took the time to type out. read them. remember ph, temperature, and........less is more.

homework, is where a great garden starts.

what spectrum is the light. I believe you need cool white. what kind of dirt did you use? and you dont give it nutes until its in the veg state and then you only give it 1/4 - 1/2 half strength. and you are going to have to invest in a timer, because its not that bad thats its only happened 2x but if you keep doing it Im sure it will have some sort of effect on the plant.
I am not a professional but anyway hope some of that helped

yea and pretty much, it sounds like you have a lot more reading to do

Get a timer. That should of been first. We all make mistakes so that's how you limit them. More reading is needed. Cheak out the stickys full of info there. There is everything you need or want to know and some you don't. Search dosnt always pull up what you want but always try first. Someone has ask every ? Out there.
