This is interesting as my wife loves microgreens but they seldom last very long. Thinking out aloud – I wonder what the solubility of Ca:K is in the starting medium? Presence of nitrate? Availability and uptake of silicon and Ca? My assumption might be that because this is solely a seed germinating type of farming, there is a lot of moisture present – IE high potassium uptake, nitrate uptake and lower calcium. Or if the greens are using more stored energy from the seed – was the seed crop grown without proper fertility? 🧐
