hi over the past week this has happened to my plant. Any help and advice would be grateful.[/ATTACH]
 
More info. What are the inside temps? Did you recently change a light or light bulb? How much wattage is going down on it? I have that happen to me when I switch to 1000w lights from a 400w. Happened twice, and now I don't use the 1000w anymore.

im only using cfls, ive got 2 100 watt equivalent 2700k
 
What kind of soil and nutrients are you using and at what strength? What is the pH of your feed and of your run off?
 
might need more blue spectrum in there, 2700k is red spectrum, if you can switch to 6500k cfl's it may help. just two cfl's, may not be enough lumens
what's in your soil? and what nutes have you given her? i wont ask about ph, i dont use a ph meter:D
 
If the lights were too close the edges of the leaves would be curing up and the damage would be more on the upper leaves. You can see by the pictures that it's more prevalent on the lower leaves, indicating that it started there and worked up. Please don't comment unless you first take all factors into account, otherwise it only leads to confusion.

lights are too close
 
thanx for all your help and advice guys. It turns out its def nute burn, my wife fed them while i was away last week but she fed them the undiluted mixture. So ive flushed and flushed and flushed and its on a pure ph balanced water until she shows signs of needing nutes, if she dose at all.
