My first cattleya

[Cheddarbob14]

Hi all, looking for some general advice on my first cattleya. Just bought it last week, 50%off at a local nursery. The good...it was half off and has great, bright orange blooms (sorry I'm not at home to give the full name, will later). The bad....pseudeobulbs are quite shriveled, and from the little bit that I can see, roots look to be in poor shape. Should I wait until it is done blooming (still has a couple buds to open) before repotting, which I would normally do, or given the situation, should I cut the bloom stem, and give a good thorough repotting to focus on the health of the plant? I'm pretty confident with the experience I've gained in orchids in general since branching out from phals a couple years ago, so looking forward to a new challenge with my catt! Fwiw I do have a probiotic, kelp Max, and a couple different fertilizers at my disposal also. Any thoughtsuggestions or suggestions appreciated!
