I'm planning to grow different herbs hydroponically: basil, sage, mint and thyme. I would like for the nutrient solutions for each herb to be the closest possible to the optimum.
For basil I found this resource elaborating on the target ppm per each nutrient, and also this answer for sufficient ranges. However, I couldn't find similar tables for the other herbs.
I would be grateful if anyone could provide such tables of sage, mint and thyme (and optimally if there was a source which provides optimal nutrient solution for any herb and/or plant).
