Possible pseudobulb rot? - Orchid Board

Part of the largest pseudobulbs on my Iwanagara Apple Blossom has a really light green color to it...almost so light...it looks like a highlighter green/yellow color, and almost feels soft in that particular spot to me. I am sure I know the culprit of this problem as I am assuming it is rot, but I could be wrong. I am sure (know) the roots are dead (rotted and dried out) on this beauty, as it is one I transfered into s/h about 4 months ago (when I first started with s/h) and didn't wait for new root growth before transferring it. At the time it had new leads growing (it this is the correct terminology) about an inch long so I thought it might be okay, and it had just finished blooming. Assuming this is rot, I am not sure what to do as the two new growths are growing from/near the base of this pseudobulb, and to remove it, I am sure I would have to remove the two new growths as well. Perhaps I should just wait and see what happens? I am really surprised that these two new growths have not put out new roots yet, I know that is the only thing that will save this 'chid. Today I did see the first sign of a tiny little root popping out as well. I guess my only questions is, does this light green area sound like rot? I thought that the p-bulb would shrivel from lack of roots, not rot. TIA!

Light green doesn't sound like rot to me. Signs of a new root sound good to me. I'd give it a chance to perform and see what happens.

I agree -- give it plenty of light and watch you don't overwater it.. even if the pb's are weak they maybe serving as backbulbs to the new growth. I would fertilize weakly and water to flush out the salts once every month.
Again if you have moved them into a fairly new environment (the orchidarium) ..
Allow them to adjust

No, To me it doesn't erk rot. I see my bulbs do this becuz of higher lighting (sunshine) it could also mean as already mentioned, they're becomming back bulbs which is why new growth has started. The newer growth should be of equal or bigger in size once matured.
Roots are comming soon, just give it more time.
