Jasmine Sambac leaves turning yellow
I bought a small Jasmine Sambac last spring. It is in the gritty mix, and since October it is under fluorescent lights (4 inch).
I fertilize at each watering (approx once a week) with 1/4 tsp Foliage Pro 9 36 and the same amount of Pro-tekt per 2 gallons.
As you can see in the photo the veins are green and the leaves yellow. According to my research it seems to be magnesium deficiency.
Can anyone advice me, what can I do to counter this?
Thanks a lot....
