Deficiencies on leaves and stems

Hey all, I’ve been growing in coco using the general hydroponics Flora series nutrients.
I recently ran into some problems on one of my photos after switching to flower. All of my other plants are strong and healthy whilst one plant is showing signs of deficiencies in the leaves and purple stems. Can anybody help me diagnose the problem. The pictures I provided are from the top, middle, and lower leaves on the plant showing the different stages of the problem. Thanks for the help!
