From my experience no, plants do not like extreme enviroments like this. What is a better answer for your rapid growth is the flush that you gave it. You may have had a build up of excess nutrient salts which was preventing your plants roots from uptaking any additional nutes. It is always good to flush out your growing medium every couple of weeks or more, so that this does not happen.
Do you feed with nutes every time you feed?
Also it may take a few days but you will begin to see the negitive aspects of the high heat. High heat also promotes mold and fungus spores to germinate and spread very rapidly. These spores can not really be avoided because they are always present in the air but stay dormant because of low humidity and low temps.
It is also harder for your plants leaves to breath in the C02 that they need, that is why I asked about C02, because when you enrich your grow room with C02 it can handle the 90 degree temps, but without c02, it is better to stay under 80F.
I hope that this help you out a bit.
