General health - need help!

[Jdrentsch]

Hello friends,

First, I want you to know that I've done research before posting but cannot seem to find a solution to my problem.

I got an orchid from a friend a few months ago. It doesn't have an identification tag on it but it looks like it is from a grocery store..so maybe a Phalaenopsis?

It was in a really small container so I repotted it in a larger pot. It is mostly bark with a little moss on top to retain some moisture.

To fertilize I spray lightly once a week with dilute "Orchid Plus".

The orchid is under grow lights with my other plants. It gets about 15 hours of light a day. They are grow lights, and produce very little heat.

Despite this, the orchid is not doing well. The leaves droop, look a little wilted and are turning darker. I have tried to remedy this in a number of ways.

Is this simply a case of over or under watering? I've tried adjusting my watering both ways but the plant does not seem to react.

A picture is attached, should it help!

I appreciate any advice you can give me.

Very best,
Jeremy
