color break? splotchy colored bloom. infected plant?

[shaelyn]

I had a handful of recent acquisitions from Trader Joe's...and this was one of them.

it started with bud blast...but the main spike seemed unaffected at first, just all the other spikes that branched off from it. the main spike still bloomed...and then put out that little blotchy flower. I had just cut the other spikes down...I tried to keep my tools clean, but I'm sure I cross-contaminated something. ><

so I've been reading it's probably virused and I need to test it to know for sure...right? I really need to know if my other plants are infected, especially the two with keiki growing and the one with the seed pod...and the one my mom gave me that I've yet to see bloom. how can I go about finding out?
