Sickly nearly dead Potinara Cattleya

[lauraokemp]

Hello. I need help with this orchid. I have had it for over 5 years and it has steadily declined mostly after I repotted her last year. She's VERY slowly growing new roots but I thought it would b e faster. She's also growing new leaves but they're very small (due to stress?). I have her under grow lights and spray with sea kelp and a rooting hormone (several times a week) called KLN. Is there any hope or should I stop? She's been under the grow light around 6 weeks now when I installed and I am hoping they're working. Thank you in advance
