Short flower spikes on Phalaenopsis

[Kittyfrex]

Having had pretty similar experience in the last two years, here's a few things i noticed
1) if leaves shirvel before yellowing, you are either under watering or have root problem
2)leaves just turning yellow, from what i experienced, can be either natural aging process or heat stress (had it happen, they survive for a while after, but takes the plant time to recover)
3) So long as you are getting spikes and your orchid had/is producing new leaves, you can think of it as good. Even if a problem arises, having stable conditions that are favourable or at least not bad for the plant buy you extra time
4) Most of my "new" phals, both those that took their time (4 years) and those that spiked soon after (under 6 month from initial bloom drop) tend to make their first spike...laughable. I have 2 Green Apple phals that, their first year and despite being healthy, made a grand total of 7 flowers. One had even double spiked. The flowers were also 30-50% of their last bloom - one spike per plant with a total of 31 flowers.
5) there is no such thing as a too large pot provided you do your substrate well - pure moss is bad in larger pots for most plants for causing fake dry (center of the pot stays wet while the edges dry). But if you fill the middle with bark and sorround it in moisture keeping moss, that can be solved. This is purely an example, as i have most of my plants in 2-3 pot sizes "too large" and all are thriving.

These are, of course, my personal observations as a new orchid grower with extensive background in non orchids (mainly "traditional" ornamental plants for the reagion as well as fruit/vegetable). From the pictures, i see nothing wrong. The flowers are on the smaller size, but that could be new enviroment thing or it could be a smaller bloom individual (you'd know that better if you bought it in bloom already). Just give it time and love, and each new spike will do better than last.

P.s. As for color, i've had 2 plants have two different flowers on the same stem at the same time. Not a huge difference; one missed some tiny spots and pink petal edges while the other one was a much darker shade of magenta on a pinkish flowered plant. No idea what it is, but i don't think it's something you have to stress about much.
