Dendrobium Yellowish Canes

[aussieboy]

Hi Everyone,

So I just bought a dendrobium aridang blue online and it got shipped with 2 flowers. The most mature cane is about 5in tall with 2 leaves and is the only pseudobulb with leaves. Apart from being a small orchid with blooms, one thing that made me wonder is the colour of its canes. All of them have a bright yellow green colour and if you place those canes towards the light, they are a bit transluscent. They have plump canes and glossy leaves but no active root growth.

A month later (today), the flowers are now done. With winters ahead of us here, I noticed one of the leaves is losing its lustre. Is there anything wrong with the orchid itself or does the color signify that its still young? Does it need more sun or was it receiving too much light? I have a more mature denphal (potted next to it on my balcony) that is dormant too at the moment but it has retained its glossy darker green color even if its staying outdoors at ~10C temp.
