I have noticed one of my plants has begun to develop black spots on the leaves but seems OK otherwise. I assume this to be a defiency of some sort? I currently EI dose at 90ml for a 450l tank which is slightly above recommended.
I'm at a bit of a loss as growth on other plants is generally good.
Please see attached photos and I would be grateful for any thoughts
Thanks Nigel
