Has anyone used SEA-90 or Cascade minerals soil booster?

I would really like to give my garden one of these products.  I have HUGE plants but they are not very productive.  I dont know why but am thinking it would help if they had more nutrients.  The concerns I have- the SEA-90 has a lot of sodium, which they say is ok but then again they are the ones trying to sell the product.  Cascade does not give a detailed analysis, but they mention aluminum as one of the main things it contains, and isnt Al supposed to be a trace metal, and not in high concentration?   Any thoughts?  I tried emailing cascade and got no response.

Oh also forgot to say that my zucchini has blossom end rot, it gets about 1/4 of my crop.

Try the Cascade Minerals website again.

Website needs work, but they will now answer with information and analysis.
