Feeling the burn

hello growers
I'm trying to grow a black kush. Before i always have grown with cfl's. Now i would like to get away from the fluffy buds, so i purchased a mars 600. my plant is 2 weeks old, its in Foxfarms ocean forest without any nutes. the light is 24 inches away. i started veg under the cfl's until the mars came in, and it was doing fine. now with the mars the heat in my 3x3 x6 tent is at 83 degrees(led's do give off heat). humidity is at 40%
any help why my plants look like ass. any help would be great. here is a couple pics to give an idea what is wrong..
thanks folks....

That's not a light issue... Probably too rich of soil at this time. A flush may be in order - no nutrients for now...

the new growth looks good so what ever happened to make the earlier leaves look like that isn't happening know. Wait and see what the new growth does and add a product like Actinovate that protects the plants from fungus and mold and get some neem oil for any bad bugs in the soil or on the plants.

I just transferred her yesterday. It got a bit worse overnight.

Never had this problem before. So I thought the light may be to strong for the little girl.

try raising the light.

Go back to cfls for a few weeks. Then break out the big boy

Ok she back under cfl's. Should i trim her dead leaves, or just leave them there?
