Phalaenopsis speciosa spots
 

The orchids seem to wake up earlier this year. Speciosa/tetraspis are all good to bloom soon or already in bloom.

This is my speciosa pots, four short spikes that are beginning to rebloom.

I find the same, mine is on it's second round of blooming this year. Yours has much larger spots!

What temperature do you grow it in? Does it fluctuate or is it stable?

I grow all my plants outside with temperature fluctuations

It fluctuates most in the summer for me, I grow in a large grow tent in my mudroom. I do not have a cooling system so temps are up to nature during the summer. Usually, the highs are ~83-85F during the day and mid to low 70s during the night; sometimes I have a couple days warmer than that. During the Winter I use a small greenhouse heater and the high temp is stable at around 74F and cools down to mid to low 60sF.
I don't typically grow outside as I have no shade (no trees on 1.5 acres of land, just pure sun!)

Beautiful! Mine does very well growing outside in the Texas heat.
