From what I’ve seen sulfur deficiencies are usually a problem for organic growers. Most nut lines have enough that if you see deficiencies it’s generally due to lockout rather than a lack of sulfides in the grow medium.Growmies I've been Reading up on NPK & PPMs; your plant will need more sulphur (400 max) than nitrogen (350 max) in its cycle
So the question arises is their enough naturally occurring sulphur in my grow to get to harvest, Google states compost contains 0.5% but what if it's been recycled or leeched.
I use GH flora nova & it contains 2% so I'm only adding a tiny amount each time. Humic acid range from 1-3% so again small amounts added to the system. Is this something to keep an eye on? Please explain why . Tia(small page below explaining link between sulphur and yield)

Sulphur is not mobile in the plant, so a continuous supply of sulphur is needed from emergence to crop maturity.www.saskatchewan.ca
Epsom salts also a good option when needed.Growmies I've been Reading up on NPK & PPMs; your plant will need more sulphur (400 max) than nitrogen (350 max) in its cycle

I reuse soil, too, with amendments, of course. I've never seen sulfur deficiency that I could identify. I amend the soil with gypsum (calcium sulfate) and Epsom salt (magnesium sulfate). Those probably provide enough sulfur. I had not thought of having my soil analyzed, but it's a great idea. I also add other amendments, like azomite and earthworm castings. I just tried adding about 10% coco coir to a plant I have growing now, and it seems to be helpful for porosity.I have been reusing soil for the last three years.
Probably wouldn’t hurt! Epsom would probably give you the quickest result. If you think you need it fast. Is this for growing indoors or outdoors?Yeh from what I can see ppl who use gypsum and epsom are set. I'm using dolomitic lime so don't have that extra sulphur in my system. Just something on the back of my mind, maybe my plants would get little boost if I added a little
