Fertilizers for microgreens

Question

Hello,
I am going to grow microgreens (broccoli, sunflower, wheatgrass) in my room (in trays).
Instead of soil, I want to use only coco-peat as the medium. (Due to the insects & etc in soil). So I’m worried about the lack of macronutrients & micronutrients. I think it is necessary to use organic fertilizers to feed the seeds, but I do NOT know which fertilizer should I use.

What is your recommendation? Azomite? Seaweed fertilizers? or other things? (including the dose and time to use)

Thanks in advance
Best Regards

Answer 1

You will not fertilize microgreens. They won't have used up their own nutrient reserve inside of their cotyledons before harvesting. Fertilizing will not be useful here, as the nutrients won't be used, and they will build up and potentially affect the flavor of your greens.
