What is the Best Fertilizer for Seedlings?

I've been on a mission to find the best fertilizer for my seedlings. This video covers the experiment I set up to test what the best fertilizer for seedlings might be. I tested 8 fertilizers and 1 bio-stimulant, to see which gave me the healthiest, most robust cauliflower seedlings with the best root systems.
