Can anyone tell me what is wrong with my plant.

Ok my great White looks like crap. My box was hot but the temp in now under control. I use B.C. nutes i water,water,feed. I water about every to days. I think its light burn but i moved my plant away from the light and its still doing it. I have 125 watt cfl and like 4 100 watt cfls. Can anyone tell me what this looks like

Looks like nute burn to me I would recommend flushing it for 15 min with plain water for few days.

what were the temps? do you mean actual watts or equivelent watts? how much have you been feeding(what strength)? whats your ph?.....we'll try to help you but ya gotta work with us and give us some actualinfo. lol, your probally overwatering and/or overfeeding. how far away did you have the lights b4? do you have a fan blowing air on the plant?

Ok Yes i have an inlet fan and and outlet fan i just added another one to the top of the box to keep the heat down which has worked. My temp at the top of the box were around 80-85 and at the bottom of the box they were around 75. I have one 125 watt cfl and the other are 100 equvalents. I use B.C nutes. I mixed the nutes as directed so its mixed with a gallon of water. When i feed the plants i use one part water to 3/4 nutes which is also mixed with water if you understand what im saying. My p.h is around 6.5-6.8 The light was like three to four inches away from the light but i have the 125 watt next to this one.

To me it looks like its ether nute burn or a ph lockout. Ether way your gonna need to flush the plant. Are you using tap water?

It doesn't look like nuteburn at all.

I'd bet it's a phosphorus deficiency.

Watering every two days seems like a bit much, the soil needs to completely dry in between waterings.

With botanicare, I feed every watering at the strength recommended. Try feeding every time or every othertime.

You do pH the water, don't you?

Are you giving your plants BC Boost or cal/mag?

Your not gonna get the actual solution because your pics are fuzzy and clear closeups would show the actual problem better

yes in the pic I could say nute burn, but I could also say light burn as there are signs of heat stress, which you acknowledge

if it is light burn I'd say you have taken the proper steps

if it is nute burn then yes a flush is in order

Good Luck

PS not hatin on ya, your pics are better than no pics for sure, it's just hard to be accurate in helpin if we can't clearly see what is happening

what about under watering, an that would mean under feed too.
