Think you are looking at a calcium deficiency there, maybe slight overwatering hard to say. Add some calmag to your next feed and keep the ec up.

Discolored Older Fan Leaf I’ve noticed a couple of the older fan leaves have changed colors. These are also fan leaves that unfortunately get pushed up against the spacebucket walls. So I’m curious if this is normal from them being pressed up to the walls or is it a deficiency? Should they be removed?
