Can I dose Alk and calcium at the same time? Is there a certain time of the day that is best for dosing one or the other?

You can dose alk and calcium both at around the same time but not parallel. Dose one and then wait an hr and then dose the next.

Its best to dose with lights on.

Depending on your growth and consumption it might be also a good idea to dose two times in 24hrs to reduce alk shock.
