Keiki advice

[SaffronZA]

Hi everyone! I did not know what this orchid was until I looked for it on this forum, I suspect it is the oerstedella centradenia. So I know what the procedure is for epiphytic orchid keikis but when and how should I repot these keikis? I understand it is a terrestrial plant so what mix must I use? Almost all of the keikis are blooming so I think I should leave them until they are finished blooming. Any advice on the treatment of the keikis and also the plant in general would be greatly appreciated.
