When is the best time to dose NO3?

[m.kristoff]

Is there a preferred time of day to dose NO3?

I just set up my DOS to dose 7ml between 06:00 and 12:00 daily. would it be more beneficial to dose when lights are out?

Most people maintain some fairly constant NO3 level, so no. Not really.

I've never seen data supporting any particular time of dosing.
