@im4satori Thanks for all the feedback! I will tweak my regimen as you suggested, but here is my thought process.
Early Veg - aimed for low TDS, so used low end values
Late Veg - I used high end values
Transition - I split the difference between high veg values and low bloom values. This mix is used for first week of 12/12.
Early Bloom - Focus on high N and K for stretch.
Mid Bloom - begins at end of stretch. Aims to begin reduction of N while increasing P
Late Bloom - week 5 or 6, aim to reduce N and P while leaving K high.
Though I seem to mostly have chased away my Ca def problems, I still notice some Mg deficiency with red spotted leaf margins. The purple stems seems to have abated, so I'm lead to believe the Mg defs are less than I normally produced, still, Hydro Buddy is giving me a hard time about adding in Mg. I think the program tries to use the least amount of components/mixtures, so Epsom isn't used as much. I can hard code a weight to unused components to force it to use at least that much of any, but doing so effects the S substantially and only having Hoagland's Bloom chart to reference, are you aware of the high and low values for Sulfur? Is there such a thing as S toxicity?
