Low 90's daytime isn't as much of a potential problem as night time temps not getting low enough.
The plants look fine to me, that you might give them a little fertilizer then just wait - not trimming yet - and see what happens when you get further towards winter.
FWIW, I'd re-pot into something a bit bigger and - depending on the soil you're using - possibly apply a weak dose of balanced ferts for several watering cycles.
It probably is just taking a break. If the temperatures are up, the soil is nice and it's getting al the right stuff, it will start up again soon I am sure. It looks great so it should be fine.
Re-potting is not an option. As I don't have room on my balcony for bigger pots. I guess I'll just take the majority advice and just give it some light ferts and see if it stars producing again towards the fall. Thanks all!
