Red Indo Krat Getting Purple

Wow stunning :-)

I agree with your,

wonderful, observation.

 

me rifat original,

big tree now.

Could be to much sun or cold weather

Definitely was helped by cold weather, but my other genetics did not change color at all. Those Red Indo seedlings have always been especially red, here's a pic from last year:

 

hmmm...I didn't really think Kratom varied that much in leaf colour, with the Red, Green, white strains being mostly arbitrary other than in ingested effect. Mine have had this type of colouring at various stages (and more so in winter)...but never that red underneath.
