Root stimulant, need opinion!

Hi all so far Im using
Ecothrive Biosys
Vag + Bloom

Shine
Biobizz Cal/mag - will be powder cal/mag soon
Allcomes in powder.

Question:
1. What would you use for roots, to boost my roots? Or Ecothrive Biosys is enought?
2. Is it ok to use different nute. line up for root stimulant? For example buobizz roots?
3. Would you use “Superthrives” with this line up?

(what else could work well with this line up?)

Thanks
