In higher heats, a lot of people kill their plants from over feeding. This is how it happens.
Lets say your summers are usually 80 degrees, and You water your plants every 3-4 days. And you feed them every 3rd watering.
Then you move somewhere that is in the mid to high 90's during the summer. You now have to water everyday, with a heavy watering every other day, and you feed them every third day like you did before.
Now during the hotter weather, your plant will drink a little more water then normal. But a lot of the moisture in the soil is lost from evaperation, the plant will drink up the water a little faster, but will still up take the nutrients at about the same amount per time. So you start to get a Nutrient build up in your medium.
So you are feeding them every 3-4 days instead of every 12-14 days. And the plant is still wanting the same amount of nutrients, when it really just wants more water.
When you go to the beach on a hot day, you drink more water because of the heat. But you do not eat that much more. Same goes with plants.
I would move that plant indoors and flush as Max has suggested. You should give them a good flushing with just PH'd water. Allow maybe 1/2-1 gallon of run off. Take this run off and mix it. Then take a PH reading of it, and take a PPM reading. Bring that info back here if you could please. I am thinking you will have a very high PH reading with a large PPM readings also. Might even be higher then you put in.
