Why spiking now?

[greenpassion]

Hello all. I discovered today that two more of my phals are spiking. One is a very large one that I think I might have mentioned earlier in a post, but today I also discovered two of my mini noid phals are spiking as well. I am so surprised because ordinarily most of these spike in mid-December. I will admit that I haven't paid as close attention, and I have changed fertilizer to MSU. I'm just so surprised. I'm hoping that my response from you guys will be that things are just so much healthier than they've been in the past. The mini phals that I have I bought as rescues, so I have really have no idea about them. I've only had them about 6 months. Sorry to make things so blurry. But I guess my question is will phalaenopsis orchids Spike and bloom more frequently the healthier they are? Or is it simply their biological makeup.? Environmentally I am doing nothing different other than paying closer attention, meaning that I have small fans keeping the air circulating, and as a hover, I am making sure they are getting adequate water and nutrients. Probably more so than last year. Or even the year before that.
