Guankalong soil for all stages?

[yodabado]

Is Guanokalong soil too strong for the seedling stage of the plant, just want to make sure I don't burn my plants from the start :S

Yes don't risk it. Use an inert soil! Feed them very lightly when first true leaves appear. I do quarter strength of what I would usually feed in veg!
