I was searching for days and feared the worst, it didn't quite look like the TRV bullseyes but it didn't match chlorosis either. I emailed Adelman today and asked if they could help me identify if it's TRV or a magnesium deficiency and Steve confirmed it's magnesium deficiency!!!!!!! He got back to me within hours too! What a major relief! I am definitely a bigger Adelman fan, which I don't even know if it's possible.
I was preparing for the worst since Joker is 3ft away from pastelroma, Nelda's joy, Blushing Princess, Rachel, and Chinook. I thought I would be taking out half the bed, since chinook was showing symptoms too.
