Beginner Gardening: What is wrong with my tomatoes?, 1 by AbbeyR

I have a beautiful plant that I started from seed in April. I know this was a little late, but it seemed to be flourishing. Lately I have been noticing a few spots and then the bottom of the plant started to look rough. The leaves feel rough to the touch. On some leaves on the underside there are little brown spots, that do not appear to be insects. It is also REALLY hot here. Over 90 every day for almost a month. The tomatoes are in a 16"pot on the patio. We water three times a day.
