Hi,
I am using AN 3-part ph perfect fertilizer with R/O water and my plants developed a Magnesium and what it seems to be a Sulfur deficiency too.
After looking for the reasons I used this nutrient calculator.
By using this calculator I figured out that the AN fertilizer barely contains any Magnesium and Sulfur.
I assume they solely rely on the tapwater to supply Magnesium and Sulfur.
If you are using AN with RO water I am interested to know how Magnesium and Sulfur you are supplementing? (ml or ppm, or both)
Some PPM stats:
AN 4-4-4 (per liter): 5ppm Magnesium, 9ppm Sulfur
GHE Lucas Formula Veg 5M-10B (divided through 3.8 to be comparable to AN'S per litre ratio): 46ppm Magnesium, 30PPM Sulfur
GHE Lucas Formula Bloom 8M-16B (divided through 3.8 to be comparable to AN'S per litre ratio): 73ppm Magnesium, 49ppm Sulfur
