Heat??

my kush was looking perfect. 2 weeks, working on 3rd node. now the 2nd set of leaves is completely curled under with yellow spots on the origional (round) leaves.... using soil, mg seed starter now, i have foxfarm for the transplant. 150Wmh bulb 10in away, (my hand felt comfortable) and 240W of cfl....temp would get up to 85 and down to 65 depending on light/dark cycle and if door open or closed...i have now removed the mh and put it under the 240W of cfl...
its not a watering issue, i have a moisture meter. i use filtered water that i let sit out...heat is the only thing i can come up with.. anyone concure

ROOT DAMAGE when i transplanted a small corner fell of exposing some root, it didnt look like it ripped the root away, just exposed it, could that be it, and if so should i put the mh back on.....and by the way the top leaves look good annd gorwing fine..please help someone no replies out of fifty views, u guys taught me how to grow this far!!!

sounds like you didnt need any help as you solved it by yourself
personnaly,I would leave the MH off a few days to confirm it is happy,then add the MH & keep an eye on it
