Short flower spikes on Phalaenopsis

[Dalachin]

I agree w NatalieS! Also, you might consider repotting after it blooms, and keeping it warm, giving lots of light, and fertilizing when growing roots and leaves, and you’ll rebloom many times, perhaps more satisfyingly than when it came with blooms.

My orchid started flowering a few weeks ago and looks great. The spikes didn't grow any higher.

The flowers aren't as yellow as they were when the orchid was bought nearly 3 years ago. Could that be caused by some sort of missing trace element?

I've been very sparing with the soluble orchid fertiliser. I may need to actually weigh it rather than guessing.

This orchid is the single surviving specimen of the 6 or so I've repotted over the last 2-3 years after they finished flowering. They've all had the same treatment but gradually all the leaves would turn yellow and drop off one-by-one.

Light and temperature can both affect color, so that flowers may look different in different bloomings.

Thanks.

I've also had Phals with a slightly different color depending on conditions, and one also has more or less spots (a stuartiana cross) each year.
Harlequin Phals like yours are also known for occasionally being wildly different from one blooming to another if the conditions were 'right' for it. I've seen threads here of people showing a plant that has normally mottled blooms which suddenly blooms a solid color.
