Some of the canisters in your RO need to be replaced. A year is too long to go without changing probably 2 of them. Contact someone where you bought the RO unit and ask them.

the filters in an r/o unit are only good for so many gallons of water. Some r/o units require the filters be changed every six months. If the filters look exhausted or dirty its time to change. An add-on DI unit would be very helpful also, that will help filter out any impurities that the filters let pass by.

you might look into getting a backflush for it also, i think they will make the RO unit last longer...

The nitrite might be a trace contaminant in the salt mix. It's not going to hurt anything. You could try a TDS meter to gauge the quality of the RO-DI output.
