yellowish leaf tips

some newer growth leaf tips are white/yellow. planted in miriacle grow soil, but just a few days ago. had gotten the clones from a friend. growth has increased, and they are under 8 42W CFL bulbs 24/7. having a hard time not flowering but trying to give them a week or two in good soil first.
thx, Bullfrog

I dont use mircle grow, but I do know that I have read many peoples plants mess up once transplanted. They transplanted from begining and the nuts are to strong for plants, this is what there conclusion was. I have not heard one good thing from that shit.. But it would be nice to have 1 positive comment on miricle grow.
Your leave its are def burn.. Somethings not right, hence your soil.gl

i would pull the lights up a lil to i think the miracle grow is no good to but my plants only like cfls about five inches away..they are clones so you dont have to worry so much about stretching....calm down and raise the lights and see if they pop back up and ahh i dont know what to say about the soil....

just got home and checked plants, growing like crazy. moved the lights up a couple of inches tonight. i've never seen such bushy plants. the stalks don't have more than a 1/2 centimeter between stems. and the stems have nodes bigger than the stems themselves. no more yellow leaf tips so far. there are just a few. i have used supersoil in the past (outdoor grow) and it was great. cheaper too. next time i'll use it. i'll keep posting new pics and comments. here are pics from tonight...
