Aerangis puncata leaf red and dying off

[nzadro]

Hello friends,

I am concerned about my Aerangis punctata. Ever since I got it, it has not been happy. It already arrived unhappy, but since then, nothing makes it happy.

The leaves grow quite small and the rear leaves turn red and die off quickly. I am attached pictures. Is it too much light? Too much fert? I can not see a pest, so I do not believe that is the culprit here. If anyone has some insight please let me know, thank you.


Culture: Grows under LED panel in an enclosure. Misted every morning. KelpMax once a month, small amount of fertilizer with watering once a week. There is some algae on the roots, which I need to clean off.
