On the link: 
http://www.juniper.net/documentation/en_US/junos13.2/topics/task/configuration/ex-series-gigabit-interfaces-cli-els.html#jd0e111

There is only a note of duplex, not about the speed: 
Note: On EX4300 switches, the interfaces operate in full duplex mode only.

I do see on a EX4300 some links in 100Mb and 1000Mb, don’t have 10Mb devices attached. 

Not sure why this is.
