My Masdevallia Measuresiana has tiny leaves
 

Hi,

I need help. I bought recently a masdevallia measuresiana (M. amabilis x M.
tovarensis). He had quite suffered from the very hot summer we had in 2003,
but I bought it...
Now, it has grown 2 generations of leaves, but each are very small,
regarding the older ones. I grow it inside (21°C) during the day and outside
(7-14°C) during the night. My over orchids do well.
Any solution ?

Thanks.
