Calmag I’d say is definitely needed, especially if you’re growing under LEDs as they seem to make my plants hungry for cal. Alg a mic is useful but not essential, it helps the plant deal with all sorts of stress (over/underfeeding/disease/temp). I use it as a precaution more than a need.
As for when to start - yes it’s true it can take a couple of days for the organic nutes to make their way in to the plant - but that is not too long, so if you checking your ladies daily you’ll spot a deficiency well before it becomes an issue and can add what you need and the plant will recover. If you try and pre-empt what they need you risk over feeding which can lead to other issues you don’t want (eg over feed nute ‘x’ and cause lock out of nute ‘y’) which will be more hassle to correct than recovering from under feeding imo.
