I haven't found (within these forums anyhow) the upper limit for sulphur in a hydro solution. I put together a rough approximation of a formula posted by a respected member here, but because of the differences in base salts that are available, the S element is going to end up at approx. 87.7ppm according to HydroBuddy. In browsing through the ShroomDr's Nutrient Formula Elemental NPK parts-per-million List! sticky, the highest I found for any commercial mix was 77, I believe.
So, is 87.7 too high if all other macronutrient levels are in check? Lemme know what you guys think!
