no one? would adding bone meal to my an iguana juice work?

Are your plants showing any other signs of a deficiency?
Are the purple/red stems on the fan leaves only or all leaves?

no other signs of deficiency. the stems are only purple towards the top of the plant on the fan leaves only.

I would say from experience that its a genetic trait. No need to worry
