Easycarbo

Sorted I will dose after lights out at 10pm daily (carb), meaning that it has till 9-10pm to use it up next day).

What about for the dosing of the profito WHEN is that best done (is night time acceptable (such as the same times as my carb dose)?)

i would think that'd be fine,
altho as truck said, it contains no phos or nitrates, which are two of the "main" nutrients plants need.

however your tap water may be high in these and if you do regular large water changes these may not be needed. but i would look into supplimenting them as adding more will not cause you any problems.
