The excessive nitrogen fertilizer probably disrupted the flower growth and changed it into a leaf growth.
It's not too unusual, although it's much more defined with nobiles. In the case of nobiles, many latent flower spikes can change into keikis.
Your type of growth can sometimes develop into an aerial keiki with roots. Or, the new terminal growth may continue for a short while, then mature and produce a truncated flower spike. I suggest lessening your fertilizer application and giving brighter light.

The second photo was taken at night for better definition, thus the bright green color. The leaves are firm and I rotate fertilizing regimens on a regular basis. She was given to me in bloom on Mother's Day 2008 and has bloomed a few times since then. The plant's growth is definitely being restricted by shelf height and other nearby plants. Nearby plants which share the same lighting include spiking, sheathing, and or blooming Oncidiums, Phal type Dendrobiums, and Cattleyas. There is also a thriving Vanilla plainiflora, and an assortment of healthy succulents in the same vacinity.
I tried moving some similar type Dendrobiums to slightly higher lighting conditions a few years ago and they promptly received sunburned leaves.
Phal type is such a general term for Dendrobiums. This one has smaller blooms that don't look anything like a Phal. This is what they look like when blooming.
Would you call this a Speiki?
