too hot for my plant?

I wouldn't worry about it. Pushing 90 becomes a problem. Some strains might not do well with it, some might do better. Who knows.
I would think it's definitely more of an environment for a sativa breed though.

In my experiences anything above 85 results in slower growth. Anything above 90 and you start having real issues like airy buds, stunted growth, leaf problems, hermies, etc. There will be people who will defend 90 degree temps, but only thing I can say about that is, they have never grown properly to see the difference.

I Agree with althor,I also found this for ya -

Things to Know
A plant’s ability to absorb nutrients is affected by the temperature, among other factors. Under high light, hot conditions, to prevent thinning of stalks, plants should be given 10 – 20% less nitrogen. Under a cool or cold regimen increase the nitrogen by 10 – 20%.
Marijuana grows well in moderate temperatures, between 70° and 85° F (21°-29° C). Both high and low temperatures slow marijuana’s rate of metabolism and growth. The ideal temperature for your plant is tied to light conditions. As more light is available, the ideal temperature for normal plant growth increases. At temperatures below 60° F (15° C), photosynthesis and plant metabolism slow, stopping growth as it waits for better conditions.
Plants kept at a constant temperature are likely to grow stouter, sturdier stems and have denser bud growth. At temperatures below 60° F (15° C), growth slows as plants wait for better conditions.
Marijuana plants are very hardy and survive outdoors over a wide range of temperatures, even including extremely hot weather, up to 120° F (29° C). However as the temperature rises from the high 70s into the low 80s (20-25° C), plants spend more energy staying cool and maintaining faster cell metabolism.
When taking the temperature of a garden, the specific area of interest is in the uppermost foliage of the plant canopy. The space between the plants may be cool, but most important is the temperature of the canopy under the lights where the plants are producing new growth.
Root temperature is just as important as canopy temperature. When a plant’s roots are kept warm, the rest of the plant can be kept cooler with no damage. Cold floors or earth slow germination and growth. Cold temperatures also encourage more of the plants to develop as males. Additionally, water temperature should be adjusted to balance out the air temperature.
It is important to keep the canopy cool to maintain photosynthetic growth. In high temperatures outdoors, use a fine spray of water from a patio mister, or something similar. Indoors, there are many ways to keep the canopy cool—using air or water-cooled lights, running the lights at night, venting the garden with filtered air, and air conditioning or air cooler units.

Another way to buffer your plants from the heat is to introduce CO2. I'm not sure what the exact mechanism is but it is likely the result of increased respiration/transpiration.
