Proper Sulfur levels in substrate

I have been having problems with too much sulfur in my plants. I have been doing soil samples with Soil Savvy test kits. My sulfur is coming at 48 ppm in the test results. The test (not calibrated for cannabis) says optimal range 6-12 ppm. I have had some major problems with sulfur and sulfates. It's in everything. I'm switching and modifying my nutrients to delete all sulfates and regulate the sulfur so I don't get a deficiency. I'm a licensed producer in Oregon. I have a perpetual system and harvest once a week. I do samples on my substrate (sunshine#4) every week. I do the second week of flowering to see where I am at and what the nutrients are pacing for the rest of flowering. I need to get an accurate optimum ppm for sulfur in my substrate so I can keep things in balance. Your help would be appreciated.

70ppm is the answer.

How did you arrive at this Number?
I see the soil test suggestions for a lot less.

That being said I use a lot of gypsum and have never known of sulfur overdose. Seems to me the more the better. I think it boosts my terps.

I don't see how you could have too much sulphur in a soil situation

I have been using this and then doing follow up research and it looks like the numbers are legit. The micro nutrient ppm's are right on point.
