My potted tomatoes are developing a very pale leafs at the start of growing tips - typical of sulphur deficiency.
I am interested in how much sulphur should be added to soil? What are typical concentrations of sulphur in soil?
These are the images. They were taken once the progression already took place. At the start, only the growing tips were pale. The other issue that springed to mind is root space. This plant is huge and was cut down periodically to foster lateral growth instead of one apex.
