It sure looks like it, but that is typically caused by excessive water uptake paired with inhibited transpiration. With a plant that hasn't been watered, the first isn't very likely, and I really doubt your humidity is so high that it results in the second, so that point in the direction of overfertilization.

If that is the case, it may have happened prior to you obtaining the plant, stored in the old pseudobulbs/canes, and is not showing up as the leaves expand.

Inheriting cultural issues from the previous grower is not something I'd considered before!
