The only way to know if it's true or not is to use the scientific method, try one with organic fertilizer and one with TTF, compare the results in regards to taste. Their dry one was better than the synthetic, liquid one, but way overpriced.
I use Dr. Earth (best) or Down to Earth.

It was expensive to buy just one, but buying 4 made it more affordable, plus it was 6 lbs vs 4. I still think it was worth it and would like to find something similar.

This is what I have tried trying to find a close match:
Coast of Maine - Stonington Blend - (5-2-4) in theory this was the best, but 2nd bag had bugs crawling so I am out.
Fox Farm - Marine Cuisine (10-7-7)
Fox Farm - Tomato and Veg - (I added dry kelp)
Tomato Maker (4-2-6)
Sustane - (4-6-4) - this is what I am currently using.

Have you found anything close?

@Barb_FL I’m using GardenTone, Azomite plus worm castings for dry and Urban Farms various liquid formulas as supplemental.

Re: the separation of TTF.

I got a great tip last year: Put the jug of TTF in your car outdoors for an hour or two. The heat will warm the salts and help them recombine without breaking your arms shaking the jug to death.
