Looking good so far...but

So it has been groiwing pretty quick....it only sprouted out of ground his past weekend and it is only been a coupe od days...its moving quick....I just need to know when i should stop 24/0 and move to 16/8.....Should I do it in two weeks when i start feeding nutrients in? also is there a specific way i should be giving it water? directly into soil with a cup? a sprayer? ext.?

WOW...........Give the seedlings 24 hours of light until ya flower. Water the plant when the cup feels dry as hell. Like a beer cup size water once a week at most. Soak the hell out of soil when watering.

really don't spray, unless you know what you are doing it just invites all sorts of fungus and bug problems. I use a turkey baster, hey it works. water when you can stick your pinky into it and it comes up clean. ok a cheap way to do it but again itworks. I am a poor indoor gorilla grower. My setup costs under $100 for 20 plants so, no ph meters or soil testers or anything . but my finger has never failed me (patting self on back, here)
