Well, this doesn't answer your direct question, but... The amount you add
will not necessarily be the amount you end up with.  The plants use the
NO3 for their own evil purposes :-).  Using your math (which I can
find no faults in, other than you seem to have accidently typed
"180000 / 0.61" instead of "180000 * 0.61"), I've been adding 0.3 ppm
NO3 for the last 8 days.  I still have no detectable amount of NO3.

You will have to experiment to see how fast your plants eat the nitrate.
