Leaves turning yellow!

[miss_georgina]

Hello!

I'm having some problems with my orchid!

I've had this orchid for 3 years now, and haven't had any problems until now.

As you can see in the photos, I've a new leaf forming. Since the flowers died back, I have actually had two new leaves, this is the second.

The plant started to outgrow its pot, so I repotted it last week. I have already lost one leaf, but thought this might be normal as sometimes old leaves die as new ones grow. But now I've got two leaves turning yellow and I'm starting to worry.

The soil is moist, but I've only been watering once a week. Maybe it's too moist?

Can I save these leaves somehow?

I hope someone can help!
