Neither , im afraid. The 2 next to(matudae and spinossima) it are displaying sings of regular growth, one growing even denser spines and tubercules.
Most of my plants, especially my mams, have entered a growth phase as of recent, this being no exception. I have mams in shadier spots than this, showing no signs of etiolation within the new growth.
I take it this is due to the shorter daytime and lower max temps
