Hoya blashernaezii ssp siariae Flowering From Tiny Cutting

Hoya blashernaezii ssp. siariae is a plant that I am currently trying to save and don’t know if I will pull it off or not. Here is one of the last rooted cuttings that I have of it, and it put out a peduncle and flowered rather than the new growth that I desired. Note the sun stressed leaves, which could be hindering it putting out a new vine.
