Well, other than calcium and related phosphorus, it might be slight potassium issue.

Yellowing and Reddening of older fan leaves
I’m experiencing a lot of yellowing that progresses into dark red blotches. I suspected a possible cal mag deficiency but after upping the dose multiple times I’m still having issues. Any recommendations on possible causes/treatments? Temp stays between 74-76, humidity around 60%

Red pattern at the bottom of the leaf
Noticed the appearance of this red pattern at the bottom of my leaf. Could this be attributed to plant stress? The new leaves are very green and healthy, so I am thinking this red pattern is associated with some stress the plant suffered in the early stages of development.

yellow/copper appearance in some leaves after first run off watering
hi! after the first run off watering the girls seemed alright, sturdy and firm but some of the leaves (one leaf, 3 plants currently) experienced copper/yellow/orange tints . this is only on old leaves so looks like mobile nutrients. could this be cal-mag issues?
