So I got me some cal mag and while I was waiting for the pot to dry up so I could feed it to the plants with the next watering, i ended up reading up on pee fertilizer and how good it is for plants. So I figured what the hell might as well, I got my little 5 year old and got her to pee in a bucket for me (figured her pee gotta be healthier than mine lol) watered it down about 1:10. So yesterday I mixed the pee fertilizer with cal mag and only half the recommended notes (botanicare pure blend pro) and lo and behold!! The yellowing pretty much disappeared over night! I think my little ones gonna be peeing in buckets more often
