Hello twd000,
Maxi grow has mixing directions right on the package. I believe it's 2 tsp per gallon of water for full strength nutrient solution. Don't get caught up trying to fallow TDS numbers. Not only are you trying to grow many different plants in the same system making any TDS values worthless. But any TDS chart is only a general starting point. There are so many environmental variables that change nutrient needs, not to mention size and age of the plant that TDS/PPM and EC charts are really only good for determining if the plants are heavy or light feeders in comparison to other plants. If your looking for a TDS/PPM/EC charts, here you go.

TDS/PPM/EC Requirements for Vegetable
TDS/PPM/EC Requirements for Herbs

P.S.
Broccoli rabb is a flowering plant, the broccoli heads are the flowers.

Many of the plants you mentioned are light feeders, but others like Kale, Broccoli and spinach are heavier feeders. A general rule of thumb, the darker green the foliage is the heavier feeder it is. Mixing the nutrients to about 80% of full strength for mature plants is generally a good starting point. Just watching your plants grow and knowing what to look for will tell you if the plants nutrients are depleted as well as too strong or week.
