I gave her too much light a couple of days ago.
The affected leaves are brighter than normal, claw downwards and are permanently droopy.
The bottom leaves of the plant are healthy.
Is it just the light stress or is something else going on?
What should i do?
If you got only those LED strips going its the opposite of giving her to much light , she is dying of light deprivation, suffocation as Organoman mentioned and most probably also some problems in the root zone.
