Hoagland solution was the basis for modern recipes adjusted based on tissue culture analysis. Right off hand, it looks like the NH4+ is very high. If you fire up Hydrobuddy, I have had good luck with the “Tomatoes - Third Cluster U of Florida” from start to finish.
In that recipe, I pull the iron down to 2.0 ppm in my micro mix and add a good fulvic acid. Adjustments are done based on growing medium, VPD and how the plants react or tissue sampling.
