Root tabs with Activ- Flora substrate

[PatO]

I’m starting a 20 long with a variety of coop plants. I have Activ-Flora  substrate to start. Would root tabs be helpful to add to stem plants or would it be redundant to start until the plants use up the nutrients in the Activ-Flora.

I would weight till they have used up the most of the nutrient in the active flora substrate and then start using the root tabs
