My Den kingianum has spike nubbins, now what?

[camille1585]

I just arrived back home in France on Thursday for the holidays and first thing I did was inspect my orchids that had stayed there and were being cared for by my sister. Extreme lack of water was the main problem,(one phal is in very sorry shape) and the kingianums did not get a drop of water in 2 months (much to my horror). The canes are extremely shriveled, some keikis died, but is seems like there are spike like nubbins coming out of the tops of the canes!

Do I start watering them on a normal schedule again, or keep the reduced watering (every 3 weeks or so) until the spikes are further along? I'm new to kingianums, so I don't know what I should do.
