My Plant is dying!

The edges on just about all my leaves are turning brown and curling up... except on the very top of the plant, but there is minor 'burning' there too. i know it isnt from heat stress because it is only under 4 26 watt cfls and about 68 degrees in my closet. Also, 4 leaves on the bottom of the plant are starting to turn yellow :( its in fox farm ocean forest soil, and today i fed it 2 tbl spoons of grow big and big bloom in a 1/2 gallon of water... but it hasnt helped as of yet... any body know whats up with my plant?

WOW, I HAVE NEVER USED GB OR BB, BUT I DO USE 3 PART VITA GROW,,, AND I ONLY USE 1/4 TEASPOON PER GALLON.
JUST SEEMS ALOT OF NUTES PER 1/2 GALLON, BUT AS I SAID, I HAVE NEVER USED IT.

JUST MY 2 CENTS :twocents:

it says to use 2 tsbs per gallon on the bottle

Sounds like you're nuting the poor girl to death...but without pics, I don't think you'll get much help...

sounds like its overfertalized to me also. did you put ther nutes before or after it started changing?
