Give me an oppinion about this fertilizer

Plants need a very little amount of food, but they need SOME. In nature,they see maybe 15-25 ppm TDS, but get that frequently. We feed less frequently, so. need to increase it. Exactly how much, nobody knows for sure, so we guess and observe, changing as needed.
I view 75 ppm N as a reasonable guess for feeding every 7-10 days.
