I am in east tennessee- have also been having extreme temps here- I also have had a lot of leaves yellow and drop early- I recently read a post by Stinky Attick where her attic has been over 90 degrees and she had a problem with yellowing leaves- I am no expert but my plants have had an adverse reaction to high temps and no rain - good luck - a real bitch to come this far into the grow season to have nature turn foul and kill or stunt plants
