As far as I know:Some of this plant has started to turn red. Is this normal? I've finally sorted my fertz problems and the plants are doing well. But I don't know everything about the plants I have.
Also, this plant has never spread. I moved it once to another location and it has massive amounts of roots. But does not spread out. (No shoots) I don't have any root tabs, but use the 2hr aquarist APT complete formula, which all my plants are doing well.
Crypts will have different colors depending on: light, nutrients, etc.
If it was green and started turning red it likely never had iron source and now it does and/or the light intensity has changed.
