funky, the distance you should be aiming for with the light is when you can put your hand at the top of the plant(s) and keep it there for about 5 seconds before having to move it. move the light up just a tad. if that's the case cool.

you probably want to look into some nutes. i use miracle grow with no problems. others say it sucks. i am looking for some different nutes (i'm still in veg). i found some super bloom at lowes for like $6. it something like 10-50-10. i haven't used it yet so i don't know how good it is. but you want a high amount of phosphorus in flower, with low nitrogen and potassium.
