Help!

Where are you keeping it? Looks like it’s suffering from big temperature fluctuations. The purple looks like it’s been getting to cold, brown crispy looks like you’ve cooked it.
The compost looks a little dry, but difficult to tell. How long’s it been in that pot? First thing I’d try is repotting into a bigger ( probably something like a 1lt )with fresh compost and keep where there’s constant temperature.
Never grown that variety, so don’t know if it’s extra temperamental, demanding / fussy.

Agreed!
