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.
