If you let the cutting bloom,it will not set roots proper or grow leafs.cut the inflo(flower) and see.
I have had it with almost all of my cuttings,and sometimes i let 1 flower to open to see if its the cutting i ordered and then cut it all off.
Do not fertilise it just treat it like any new cutting.

Thanks Michael! Where do you buy the cuttings from? in Europe I mean.

I received some cuttings with inflos but didn't remove them. I was lucky because mine did produce lots of foliage along with the inflo and rooted within two months. If you don't have any foliage or roots you do need to remove the inflo so that the plant's energy can go to rooting instead of flower development. It's just so hard to cut off that inflo. There's no need to fertilize or water if there's no roots but you can mist the tips with water. The hotter it is the better for root development, especially bottom heat to warm the soil. Don't begin to water your plant until you have several large leaves. Good luck.

I have already cutted the inflo. There are some small leaves that do not grow for the last 2 months and they are just there without any progress. I spray them with water every night. What else can I do? Let's hope that something will change.. I wonder if in the middle of the summer can grow roots feeding together the small leaves.!!

Warmth is the most important thing needed for rooting a cutting. You might want to provide some bottom heat. I use a seed mat that maintains a constant temp in the mid to upper 80's. I don't know if daily misting is necessary because your plumie is in a conservatory and the humidity is probably pretty high.
