Sorry about your close call. I noticed that nute burn on your tips. I did mine till they showed slight nute burn then pulled back on the nutes.
They do warn about nutes on young plants but only for the novice grower. Overloving your girl is very common .
And you should check youtube.com for grow vids. I learned alot there.

I intend to use CFL all the way. I've got 246W = 18K Lumens. I realize the lost lumens but I'm testing the spectrum of CFL's effect on Buds.
Come check me out, I'll catch ya later
