Ah, idk how ppl haven't noticed the early signs of sulphur defiency.
Epsom salt is my go to for mag/sulphate. And it a key nutrition that enable the rest of the nutrients to do their job 100% instead if only doing 70% of their job as they didn't have what was needed to get 100%.
So, I use Ultra Pure Epson salt. But, if you go to any pharmacy. You'll easily pick up a 200g bag of Epsom Salt (make sure it has no lavender or any aloe Vera)
I use it, you can make a 250ppm feed and use it as a foliar spray. So, you'll get an injection of mag/sulphate in ur sub and on your soil. Do the foliar spray after lights out as if it dries to quick it'll block pores.
