Of course, in this case I was analyzing
Rhyncholaeliocattleya Memoria Anna Balmores

Select that (now in bloom) to try to understand how to read the document

Thanks!

New roots or no new roots is irrelevant, I know some people religiously only repot when there is a new root and that is fine but I personally do not wait that long, if I had in the past I would have lost orchids I was able to save instead.

I will emphasise this again if the substrate is going bad, the orchid will not be happy and won't produce new roots. Only happy orchids produce new roots. Ie orchids that have been freed from their smelly old substrate and given a clean fresh new clean out around their feet.

You can wait and wait and wait and decide the orchid is not ready to be repotted as no new roots are forming and sometimes it will die which is out of our control or you can take matters in your own hand, give it a fresh substrate, encourage new roots to form and prevent the orchid from going downhill before it happens.
I routinely see both approaches being used. I am certainly more proactive. The worst that can happen is that an orchid gets set back a little from a rough repot but practice makes perfect and the more experienced the better one gets at it so there will be less repot stress every time.

The most annoying thing about growing orchids is watering and repotting. The good growers water regularly and repot when its needed, the bad growers water randomly and avoid repots.

You make your own conclusions

Thank you! I understand and I believe the roots of one of them are suffering because the Medium is already discomposed,

I love to repot, cure them, made them happier in some kind of way.
