Beallara Marfitch 'Howard's Dream'- sudden pseudobulb wrinkling during bloom

[Skippersmom]

I have been doing orchids and other plants for years. Posting in Beginner discussion as this type of orchid is new to me.

Live in Nebraska. Orchid is an 'insider' but only in my possession since July 1.

This Beallara Marfitch 'Howard's Dream' came from an orchid vendor. It was in full spike – no buds open. The pseudobulbs were full smooth and shiny. The buds did not progress for about a month, figured that was shipping shock. Was running water through & out about once a week. Then a couple began to progress to open and it seemed that when I would water, a few more would perk up, etc. I have no been watering more than once week. No soaking. Nothing else added. I palpate down about an inch to figure out when to water.
It finally opened up fully around Aug. 10th. When the buds opened up, it was like ‘boom’ – nearly all at once over about 2 days. It had been in indirect light in a south exposure kitchen window.
I left town for a few days, got back Monday and the pseudobulbs are shriveled. I ran water through right before I left.
It is in a 4”x4” black plastic typical greenhouse pot. Cannot see the roots of course. With the ginormous size of the pseudobulbs and the very long loaded spike, I have been reticent to pop it out of the pot to see if it’s too wet, rotting roots, etc. Don’t want to snap the spike.
My ? is, would a mass bloom like this cause enough water demand to draw hard on the pseudobulbs in spite of what I considered reasonable watering. Is this typical? OR Would I have to be concerned that I really have rotting roots?

Thank you in advance for your experienced and wise analysis.
