I know that CO2 is used during lighted hours, and not used during the

Is there some sort of similar rule to follow regarding nitrates? Do
the plants absorb them during the day, during the night, or
constantly? Is there any real benefit to dosing in the morning, or
evening?
I do it when I remember. I really don't think it makes any difference
at all.
