I have 3 different phals pictured, and I think they are all spiking within a few weeks of each other. The last pictured phal, has this growth overnight. It may be a little soon to tell on the third, but I am pretty confident the first two are spikes

I am hoping my Sogo Vivien joins in, when I bought it it was going out of flower. Of my 8 phals I think I have 3 so far with spikes. I must be doing something right this year!
