what i learned from my first grow,

1more lumens equal more bud!!!
2get you lights as close as possible w?o burning your baby, from what i see your lights are way too far awy
3once it starts growing get it into a bigger pot
4dont apply fertilizers directly to plant (made that beginner mistake!)
5have lights on an 18/6 cycle till plant is about 1/3 the height you want at maturity, once there switch lights to 12/12
6if u clip every two nodes you will have more main kolas at maturity, just make sure u clip at an angle right above node.
7use an oscilating fan right from start to build up stem strength, otherwise your gonna be tying your baby up at the tail end of things!!!

happy growing!!
