First time mommy of a budding oncidium-is there trouble?

[greenpassion]

Well, I am (hopefully) soon to be the proud mommy of my first blooms from an oncidium ( I think it's an oncidium) and I'm really anxious. I have a phal that spiked, and the spike was visibly growing in length each day, but suddenly the tip got off color, and it looked ill. This phal spike then started growing again from the side of the 'ill' tip, and as we (I) speak, it's once more on it's way-but this post isn't really about that-just wanted to add a little background. The plant in question now (the oncidium) has two fairly large flower buds, but I'm not sure if they'll open. I'd post a pic but there are issues with this computer at the moment. Anyway, the flower buds are a yellowish white, which could just be an indication of what color the flower will be-or, it could mean that it's getting sick. ??? Am I just being a worry wart?

Hard to say without a pic. Could be white or pale yellow blooms, could be blast

cant say without pics....sounds like it might be a humidity issue tho, are they on gravel trays?

This plant is in S/H, on a heat mat, under Orchid Webs LED lights. It's been putting out new leaves pretty robustly, and the roots that I can see thru the glass (I have all my orchids in clear glass vases with a hole drilled a few inches up from the bottom) are all healthy looking. It's with many other ordchids, all on the glass sheet, all in S/H, and I'd think due to the S/H, the humidity level would be fine. I'll try to post a photo at some point.
