Soil prep question

[saltybluegrass]

so i watched the first four inches you tube and understand the rooting philosophy but want to know if you can add to a coco grow the rooting nutrients in the rockwool or Coir when prepping for seedling?
This answers why my plants are 4 inches shorter than the videos i watch - the first moments of life are precious-

Not sure I understand what u typed

But

In Coco starting with 1/4 strength nutes when watering as a seedling makes a huge difference since Coco has no nutritional value

And never compare your plants with others at a similar age, way too many factors at play, mainly strain and growing ability

just focusing on the root formation in a rockwool then transplant to its pot in coco- Along with the 1/4 nutes , Is there a root additive to add as well? Is mykos about the best you can dust the rockwool with or another rockwool prep ?

Get away from rockwool, bad stuff, to easy to drown and kill seeds
Get root riot cubes or similar

I never use any root addative. I just start low nutes right away
