I am trying to get my ppm to around 400. After watering the PPM was 197 so I added some CalMag and some Big Bloom to 1 gallon of water and tested the gallons PPM, which only came to 200 after adding 3 teaspoons of Big Bloom and 2 ml of CalMag. I was nervous about over doing it so I used that and tested the run off. The run off only tested at 226 PPM. How do I get the PPM up to the desired level without going over and hurting the plants? Do I need my gallon solution to be upwards of 500 PPM to bring the soil run off to 400? Do I need to use more than 3 tsp of Big Bloom? As always, thanks for the help.

Your plants will all have different needs. The good thing is they are eating pretty good. Just adjust future feedings according to how they are eating. According to the numbers, they all want more food except for Crystal. Your ph seems okay. Try to keep it between 6.2-6.8.
