Nutri-Sol was an early hydroponics high N and very high K feeding formula with a rating - if i remember correctly of - 20-20-38 just as growing only in vermiculite was an early hydroponics method.

In other words, what you were doing was a rough method of old hydroponics.

There are any number of modern hydro fertilizers available today with similar ratings IF hydroponic growing using their materials is what you want to do.

Of course hydroponics has moved far beyond those old methods and materials now so you will need to learn about new media as well as fertilizers for it to be effective. Check out the Hydroponics forum here for more info.

A personal observation if I may. There are many ways to grow tomatoes successfully and old remembered tastes aren't always as good as we think we remember. :)

fully agree.
There are many ways (soil, nutrients, climates, ..) that one can grow tomatoes successfully. The TASTE issue, relating to one's memory can be perceptive, nostalgic and personal.

thank you so much Dave- I realized it was a hydroponics method but just did not have the formulation. Now I have something to go on to try the experiment again. I know time can enhance the flavors of one's memories, but trust me, these were the best tomatoes ever! :)
