Camrbria and Miltonia help

[AKB]

I have five cambria and one miltonia and they are not flowering except one but keep on giving new green leaves and growth. Also Miltonia has a zig zag leaf ends. i remember when i bought them that one of them had a scent but not sure which one now, any suggestions?

I water them once a week in the shower and let them drain and keep them by the window. i keep them all together so i am not sure why one gave flower but not the others. i give orchid food once a month.

attached are the photos. i remember them being all different colors so only the orange one flowered.

Welcome to the forum, the concertina folds on the leaves of the plants usually mean they have not had enough water at some stage. The other leaves look healthy enough, so obviously you have rectified that. All orchids of the same kind do not necessarily flower all at the same time. I would suggest you download some culture sheets, that will tell you exactly what they require. AOS | Members Only Area

I'm no expert w/these types of orchids but IME, when an otherwise healthy orchid isn't blooming, it's usually a light issue. Meaning the plant isn't getting enough.

Could be the pictures but your leaves look pretty dark...that would also be an indicator of insufficient light.

The "zig-zag" leaves...or pleated leaves...is a result of insufficient water uptake. Your pbulbs show some shriveling and this is caused by the same thing.

Insufficient uptake of water could be from not enough watering OR from too much watering and/or something suffocating the roots causing them to rot. When was the last time you checked the roots?

If the roots are in poor shape, this could also be a reason for your lack of blooms.
