Phal. Schilleriana Spike Development Stall

[jiblylegs]

Hi Everyone,

I've got this phalaenopsis schilleriana that began spiking >1 month ago, and the spike seems to have stalled or taken a break. In the meantime, it has grown a new leaf and is growing plenty of roots. Does anyone else see this plant taking a long time to grow this much? Many other warm/hot plants of mine have started spiking after it and are much further along development wise, so I don't think it's anything environmental.

Thanks
