Outdoor Heat Stress?

[4fingerlid]

In So Cal the weather has been 100+ for the last week or so. I was gone for 3 days and when I got back a couple of my plants that were in 3 gal pots were really drooping and looked like they were starting to shrivel up. I watered and then gave them some nutes. They are coming back but some of the leaves in the middle of the plants are yellow. Is this normal stress from the heat and from needing water or could this be something else?
Sorry I dont have pics.

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

Yup, high temps will cause leaves to yellow.
Outdoors where there is more air circulation, as long as you keep everyone watered, a heat wave should not give you too much trouble. Tropical sativas should take the heat best.

Thanks for the replies. It seems like the week long heat wave is starting to cool down. I really thought these plants were dying when I first saw them in the evening after coming home. Too close to harvest time to have a catastrophe on my hands!
