I had tried most tricks over time to get it to flower including different fertilizers, day length changes, putting it outside in the greenhouse during the summer. I tried different types of grow lights and nothing seemed to do the trick to make this one bud up. Finally I noticed a peduncle starting to form tiny buds in late December of 2021; it took me quite a long time to really believe it was finally happening, but it made steady progress and the blooms finally opened up in Mid-February, 2022.
