Myrmecatavola Frances Fox Root Tips Stop Growing

[Chani]

Hi all,

Although I first started growing orchids about 6 years ago and have posted here a few times, I still feel I am very much a beginner. To that end, here's what's likely a very simple question, and yet I can't find an answer to it.

What might cause a Cattleya or a Catt hybrid's root tips to stop growing? Or in my case, more specifically the Myrmecatavola Frances Fox. I purchased it a year or two ago. It was in a net pot, coming from Florida, with a ton of roots. I repotted it into a clear, slotted pot. That...was a poor decision. It has barely put out any roots since then and when I do finally see new root tips and get all excited, soon enough there goes my green tips. All white with no new growth. I imagine it has to do with watering - too little or too much. So which is it? What would cause the root tips to stop being active like that?

Thank you in advance to anyone who answers
