I got a blue dream clone off a buddy of mine about 2 weeks ago and its growing well under a 120 cfl. its been under 24/24 for about a week now and im wondering when i should change it and what to. also im wondering what would be most reccomended to buy for nutrients. i will add pic later but for some reason it has this one giant single leaf growing and some curly things which only just appeared over the last 2 days..what is going on? somebody please help!
